01 / FAQ
Frequently asked questions.
Open a question to read the complete answer. Start here when you need a clear explanation about the community, the Classroom, vendors, ordering, testing, or the tools.
Getting oriented
Where should I start?+
Open the Classroom and begin with the Welcome New Members or New Trial Members course. Watch the welcome video and review the resources there first so you understand how the site is organized. Then browse the Community and use its search bar to look for specific peptides, vendors, countries, payment methods, testing topics, or ordering questions.
What is the Classroom and what can I find there?+
The Classroom is where you will find everything you are likely to want from the group, including vendor information, useful utilities, and the different tools we have built. Make yourself familiar with everything available there because it contains a lot of the group’s most useful material. If something is locked, it simply means that your current membership level does not include it yet. You are always welcome to upgrade when you want access to more.
What should I do before I post?+
Search the Community before starting a new discussion. This is one of the most important habits in the group: it often answers your question immediately and prevents duplicate discussions from burying useful information. Open the Community tab and use the search bar first. Try different versions of the term: a peptide name such as retatrutide, a shortened name such as Reta, a country such as Australia, an informal term such as Aussie, a topic such as shipping or testing, or a product code. Read both recent and older results. If your first search does not find anything, try a shorter term, alternate spelling, abbreviation, or related phrase. Once you have searched, write a focused question with the useful details included.
How do I tag someone in a post?+
To get a member’s attention, type the @ symbol followed by their name in your post or comment. Select the correct person from the suggestions that appear, then finish your message. Tag only people who are relevant to the question, and avoid tagging someone repeatedly or in unrelated discussions.
What should I include when I post a question?+
Include enough detail for other members to understand what you are asking. Depending on the topic, that may include the peptide name, product code, strength, vendor, country, shipping stage, or tool you are using. Do not post private payment information, complete wallet addresses, or protected vendor contact information publicly.
What is the difference between the membership levels?+
Trial access, when available, lets you explore the community and selected resources. Standard membership provides access to a limited selection of vendors, tools, price information, and Classroom resources. Premium membership unlocks the complete vendor directory, full pricing resources, premium tools, testing resources, and the complete Classroom library. Current inclusions are controlled by the Plans page and the Classroom access shown on your account.
What are the benefits of being a member?+
The core benefit is access to the best wholesale vendors we have found in China, including vendors with highly competitive prices, products members are looking for, encouraging testing results, good communication, and reliable shipping. Membership also gives you the Community, where members share experiences and help one another make better-informed decisions. Additional member benefits include exclusive vendor deals, group testing at the $99 member price, further vendor discounts, and the member discount for the OptiPin peptide-tracking app. Look through the Classroom and Vendor Contact Guide for the benefits and offers available now.
How do I upgrade?+
Open the Plans page or select a locked course in the Classroom. Choose the membership option you want and complete the upgrade. If content remains locked afterward, confirm that you are logged into the correct Skool account and opening the correct Standard or Premium version.
Vendors & ordering
Where do I find vendor information?+
Open the Vendor Contact Directory in the Classroom. Make sure you open the edition that matches your membership: Premium members should use the Premium Members edition, not the Standard Members edition, so you see the complete set of resources available to you. The directory contains the current protected contact information and direct links for that edition.
Why should I check the Vendor Contact Guide before ordering?+
Always open the current Vendor Contact Guide before you send a message or payment. Vendor phone numbers and other contact details can change, and an old number or forwarded screenshot may belong to an impersonator. Use the latest contact information posted for your membership level so you reach the right vendor and reduce the risk of being scammed.
How do I get member discounts from vendors?+
The group uses our collective buying power to negotiate better pricing. Some vendor discounts are already included in the prices shown in the tools and price sheets. For others, you need to mention that you are a member of the Peptide Buyer’s Guide when you place your order. The Smart Order Builder can insert that language into your message automatically, but always read the Vendor Contact Guide for the specific vendor so you do not miss a member-pricing instruction.
How are vendors selected and vetted?+
Before making a vendor public in the community, I obtain samples from the vendor and test them. If those results come back good, I place a blind order using a different account, a different name, and an address in another city so the vendor does not know it is me. I then have those products tested again. During that process, I also evaluate communication, shipping times, responsiveness, and how the vendor handles the overall ordering process. Once a vendor meets all of those criteria, I consider them a fully vetted vendor for the community. Occasionally, I may add a vendor before all of the testing is complete, but I disclose that clearly. I will usually only do that if they offer a unique product or something members are specifically looking for. I am not interested in simply collecting vendors; I will only add another one if they bring something concrete to the group, such as better pricing, faster shipping, or unique products that our other vendors do not offer.
Is there one best vendor?+
No. The best choice depends on what matters most for your order. One vendor may have the lowest listed price, another may ship faster, another may communicate more consistently, and another may carry a product or strength that others do not.
What is the Smart Order Builder?+
The Smart Order Builder lets you select products and strengths, compare current listed prices, review vendor options, and see whether ordering from more than one vendor may reduce the total listed cost. It can also create a message that you can review and copy into WhatsApp. It is an ordering and comparison aid—not a recommendation, inventory guarantee, or medical tool.
What does ‘not available in this strength’ mean?+
It means the vendor may carry the product but not the particular strength you selected. If alternate strengths are shown, you can choose one of those options or ask the vendor whether another strength is currently available. Recalculate the order before assuming the original comparison still applies.
Do vendors sell individual vials?+
Our international vendors sell kits, not individual vials. Kits commonly contain ten vials, and the available strength and price are vendor-specific. If you do not want a full kit, are testing a product, or need a faster domestic option, Easy Peptides is a U.S. resource that sells individual vials. Look for the 10% member discount when ordering there.
Why might the price in a tool differ from the vendor’s quote?+
The live tools and price resources are kept current, so the listed price should be accurate in the vast majority of cases. A difference is still possible if a vendor changes a price, availability, shipping, payment option, member discount, kit size, or minimum order after the latest update. Before paying, it is always wise to confirm the final product price, availability, shipping cost, payment options, and minimum order directly with the vendor.
How long does shipping take?+
Shipping times vary: some vendors are quicker and some are slower. Read the vendor’s shipping expectations in the current price guide, then search the Community for that vendor to find recent member reports about how long orders are taking. The first tracking number may show limited activity until customs clearance, and a second domestic tracking number may appear later.
How do time zones affect vendor replies?+
Most vendors communicate through WhatsApp and are in China, often 10–12 hours ahead of you. When it is daytime for you, it may be the middle of the night for them, so a reply may take time. The Vendor Contact Guide now shows the local time for each vendor. Check that clock before messaging, plan for roughly 24 hours when appropriate, and avoid repeated daily messages because they do not speed up fulfillment.
Do Chinese vendors ship to every country?+
No. Chinese vendors cannot ship to every country, but the vast majority can ship to many destinations. Customs rules and import requirements vary. We have members from many parts of the world sharing current experiences in the Community. If you are unsure, ask in the Community or confirm directly with the vendor before ordering.
Is the site useful if I am outside the U.S.?+
Yes. The Community includes members from all over the world, and the Maps tab shows how widely the group is spread. The U.S. is our largest concentration and some resources are U.S.-only, but we are actively working to add more useful options for members in other countries.
What payment methods do vendors accept?+
Cryptocurrency is the normal way this group is set up to work, including options such as Bitcoin, USDC, or USDT. I strongly recommend creating and verifying a crypto account before you are ready to order. You do not have to use crypto, but having it ready gives you many more vendor options and usually makes the process go much more smoothly. Services such as Wise, Cash App, or other methods may work as alternatives with some vendors. Before sending funds, confirm the exact currency, network, wallet address, amount, and payment instructions. Never assume an old payment address is still valid.

Ordering wholesale research peptides: realistic expectations
What to expect before placing an international order
Wholesale research peptides can save you an extraordinary amount of money, and based on the orders and test results members have shared, we currently have a perfect record to date: every member who has reported ordering has received the peptides they ordered, and I have not received a report of a peptide failing an independent test.
But international ordering is not Amazon Prime. Customs, fulfillment, time zones, tracking, payment, and testing all follow their own process. I put this guide together so you know what to expect before placing an order—and so the potential savings come with realistic expectations.
The savings can be enormous
One of the main reasons people use this process is the price difference.
Depending on the product, the savings can be ten times greater than what someone was paying previously. In some cases, the savings compared with retail prescription pricing can be dramatically larger.
For example, a month of a prescription product such as Zepbound can cost roughly $1,200 at retail, depending on the circumstances. A research-product vial containing the same named compound may sometimes cost around $10 through a wholesale vendor.
Those are not equivalent products in terms of regulatory status, quality controls, pharmacy oversight, or guarantees. The lower price comes with additional uncertainty and responsibility. Still, the potential savings are the reason many people consider this option in the first place.
Ordering directly from China is not a certainty-based process
If you need absolute certainty about delivery time, product availability, or regulatory oversight, ordering wholesale research peptides directly from China may not be the right option. A prescription filled through a licensed pharmacy is designed to provide a more regulated and predictable process, although no system is perfect.
Direct international ordering can save a tremendous amount of money, but it also involves more uncertainty. Customs, shipping, vendor communication, production schedules, payment systems, and product availability can all affect the experience.
For members in the United States, we also have two domestic vendor options where the product is already located inside the country. Using one of those vendors removes the international customs portion of the process, although other vendor-specific risks and policies still apply.
Customs is outside everyone’s control
Your vendor does not control U.S. Customs. This group does not control U.S. Customs. Only the government agencies handling the shipment have control over that part of the process.
Right now, international shipments appear to be clearing customs smoothly, and many orders are arriving in about a week. But that is not guaranteed to continue.
I have been ordering for years and have seen cycles where everything moves quickly, cycles where U.S. Customs slows down, and periods when additional inspections in China delay outgoing shipments. Earlier this year, I had an order that took approximately five weeks because of customs delays.
A shipment can also be delayed during an international handoff or selected for additional inspection. A delay does not automatically mean the vendor did anything wrong.
Enjoy the fast cycle while it lasts, but do not mistake current speed for a promise about future orders. Do not place an order if you need it by a specific date.
Vendor communication takes patience
All of our vendors communicate through WhatsApp. Depending on where you live, the vendor may be 10–12 hours ahead of you.
To make this easier, the Vendor Contact Guide includes the local time for each vendor. Check that before sending a message so you have a realistic idea of whether the vendor is awake and likely to respond.
When it is daytime for you, it may be the middle of the night for them. Planning on approximately 24 hours for a response is reasonable.
After you pay, the vendor still needs time to prepare the order, confirm the products, package everything, create shipping documents, and hand the shipment to the carrier. That process can take several days.
If you order today and ask for more information again tomorrow, the vendor almost certainly will not have anything new to tell you. Repeated daily messages do not speed up production, packaging, or shipping. In fact, they will probably slow things down by creating unnecessary back-and-forth and pulling the vendor’s attention away from fulfillment.
Send one clear message, provide the information they need, and then give them reasonable time to complete the next step.
Chinese holidays, weekends, production schedules, and unusually high order volume can also slow things down.
Payment methods
Some vendors accept payment methods besides cryptocurrency, and those options may work well for certain members.
Crypto, however, is the most universal payment method in this market. Once you understand how it works, it is often the simplest and most reliable way to pay international vendors.
There is a learning curve when setting up a crypto account, but the process becomes much easier once you have done it a few times. If you plan to order from international vendors, it is smart to set up your crypto account in advance rather than waiting until you are ready to place an order.
Always verify the payment instructions carefully. Use the current contact information in the directory, and be especially careful with wallet addresses, networks, QR codes, and payment screenshots.
Tracking numbers may not tell you much at first
International orders generally have two stages of tracking.
The first tracking number is usually an international or pre-clearance number. It is not going to provide the normal door-to-door updates you expect from a domestic shipment. You should expect it to show little or no useful information until the package clears customs.
After the shipment reaches the United States and is transferred to a domestic carrier, you may receive another tracking number. That is usually the number that provides the familiar delivery updates and estimated delivery date.
The first tracking number is still useful for identifying the shipment, but do not expect it to show meaningful movement until the customs portion is complete.
Testing provides useful information—but not certainty
We regularly spot-test products from vendors, and members also test products independently and share their results with the group.
So far, we have not received a report of a failed peptide test. That is encouraging, but spot-testing cannot prove that every vial from every vendor will always be correct.
A test result is a piece of the puzzle. It gives you information about the particular sample that was tested. It does not automatically prove that every product, every vial, or every future batch will be identical.
• A problem at the original manufacturing facility
• Variation between production batches
• Poor storage or extreme temperatures during shipping
• A product sitting too long before use
• A labeling or fulfillment mistake
• A problem that develops after the product leaves the vendor
A failed test would not automatically prove that a vendor intentionally did anything wrong. It would mean that the specific sample tested did not meet expectations and should be investigated.
If independent testing is important to your personal risk tolerance, test your own product. Our group testing is helpful for identifying general vendor patterns, but it cannot replace testing every product you personally receive.
Verify the details before paying
Before sending payment, confirm:
• The vendor’s current WhatsApp contact information
• The exact product, strength, quantity, and price
• Shipping charges and expected timing
• The payment method and payment instructions
• The vendor’s reship or refund policy
• Whether the contact information came from the current verified directory
Scammers sometimes imitate real vendor accounts, especially on messaging platforms. Do not rely on an old phone number or a forwarded screenshot. Always verify the vendor’s contact information through the current Vendor Contact Guide before sending payment.
The group’s role—and its limits
This group shares information, vendor experiences, testing results, pricing, and ordering guidance. We do not control the vendors, customs, shipping carriers, payment services, or manufacturing facilities.
We cannot guarantee:
• Delivery dates
• Customs clearance
• Product availability
• Future pricing
• Vendor response time
• Product quality in every future batch
• Refunds or reshipments
The goal is to help you make a more informed decision and understand the risks before you place an order.
Patience is part of the process
Even when people understand how international ordering works, they can still become impatient. But patience is not optional here—it is part of the transaction.
This is not Amazon Prime. Your order may need to be prepared, packaged, transferred to an international carrier, transported across the world, cleared through customs, handed to a domestic carrier, and then delivered to you.
The fastest way to receive your order is usually to let that process run. Allow roughly 24 hours for vendor replies, several days for fulfillment, and additional time for international shipping and customs.
If you need a firm delivery date, international ordering is probably not the right option.
The bottom line
Ordering wholesale research peptides directly from China can be extremely affordable and, based on our current experience, can work very well. In some cases, people may save ten times what they previously paid—and sometimes far more compared with retail prescription pricing.
But it is not the same as walking into a local pharmacy and receiving a product through a fully regulated domestic supply chain.
Plan for delays. Be patient with international communication. Verify payment instructions carefully. Do not assume the first tracking number will update immediately. Understand that group testing is a sample of what a vendor is providing—not a guarantee of every vial.
The potential savings can be extraordinary, but the process involves more uncertainty and personal responsibility. The best approach is to understand both sides of the decision and make an informed choice you are comfortable with.

Bacteriostatic water (BAC water): my updated thoughts
The one thing I don’t like to gamble on
GUIDANCE
Bacteriostatic water (BAC water): my updated thoughts
The one thing I don’t like to gamble on
There’s been a lot of discussion about bacteriostatic water lately, and I know I wrote a post about my thoughts on BAC water some time ago.
Because that post has been around for a while, I wanted to repost it with a few revisions, additional sourcing information, and some clarification for anyone who may not have seen it before.
First, I want to be clear: I am not saying the BAC water included with peptide orders is automatically bad. Lili, for example, has consistently included BAC water with my orders at no additional cost, and I have used it without problems. I’ve also seen several vendor-supplied BAC water samples independently tested, and I have not personally seen one fail.
That said, I personally choose to use Hospira bacteriostatic water made by Pfizer.
💡 WHY?
For me, it comes down to minimizing variables. Peptides in powdered form and bacteriostatic water in liquid form have different storage and transportation considerations. Once I am already spending money on peptides, using a pharmaceutical-grade product is one way I personally reduce uncertainty.
Hospira is widely used in medical settings, and it is the product I personally feel most comfortable using.
That is my personal preference—not a claim that the BAC water included with your orders is necessarily bad or unusable.
🌎 IF YOU ARE OUTSIDE THE UNITED STATES
Hospira may not be available everywhere, and the sources below may only ship within the United States.
If you are outside the U.S., I would first suggest finding out what bacteriostatic water hospitals and medical facilities in your country commonly use. Then, see whether that product is legally and practically available for you to purchase.
If hospital-grade bacteriostatic water is not accessible, I do not want to imply that BAC water from Chinese vendors is automatically bad. For some people, that may be their only realistic option.
I have seen several vendor-supplied BAC water samples independently tested, and I have not seen one fail. Based on that experience, I do think it can be a reasonable option for some people, provided the source is known, consistently used, and handled appropriately.
⚠️ IMPORTANT COUNTERFEIT WARNING
Believe it or not, counterfeit bacteriostatic water using the Hospira name can appear online.
Before purchasing, make sure you are dealing with a reputable medical-supply source. I would avoid buying it from unknown marketplace sellers, Facebook groups, random individuals, or anyone whose source cannot be verified.
An inexpensive product is not worth taking a chance on if you cannot establish where it came from.
🧴 SOURCING OPTIONS
For a single vial, this is the best source I have personally found:
For anyone who wants to stock up and purchase a case, Medex Supply offers a 30 mL, 25-vial pack:
That is where I personally obtain my Hospira water, but you are free to source it wherever you are most comfortable.
✅ THE BOTTOM LINE
If Hospira—or another reputable hospital-grade option—is available to you, that is my personal preference.
If it is not available, a known and consistently used vendor source may be a reasonable alternative. I do not think the choice is as simple as “hospital-grade good, Chinese vendor bad.”
The source, packaging, storage, handling, and testing history all matter.
As always, this is my personal approach—not medical advice. Use your own judgment, follow applicable laws and product labeling, and consult a qualified medical professional when appropriate.

GUIDANCE
Looking for an oral GLP-1? Start here.
Orforglipron—also known as Foundayo
I realized that some members may not know one of our listed vendors has an oral orforglipron option available.
For anyone researching a GLP-1 option that does not involve injections, this may be worth taking a look at.
🔎 ORFORGLIPRON — ALSO KNOWN AS FOUNDAYO
Foundayo™ is Lilly’s brand name for orforglipron, a once-daily oral GLP-1 medication recently approved by the FDA.
⚠️ IMPORTANT DISTINCTION
Foundayo is Lilly’s branded prescription product. The orforglipron listing in our vendor tools is a separate research-product listing from one of our vendors, provided for identification and price comparison.
💰 CURRENT LISTED PRICES
One of our vendors currently lists:
🔹 ORF6 — 6 mg, 100-tablet pack — $120
🔹 ORF12 — 12 mg, 100-tablet pack — $200
That works out to approximately:
💵 $1.20 per tablet for ORF6
💵 $2.00 per tablet for ORF12
So the lower-strength option is roughly about a dollar per tablet—remarkable for such a new product category.
These are the current single-package prices shown in our tools.
The per-tablet math above is not a dosing recommendation.
🔍 HOW TO FIND IT
1️⃣ Open the Smart Order Builder
2️⃣ Search for Orforglipron or Foundayo
3️⃣ Select the strength you want to review
4️⃣ Use the available vendor information to confirm current availability, shipping costs, and payment options before ordering
💡 If you were looking for an oral GLP-1 option, search Orforglipron in the Smart Order Builder and take a look.
