The Twelve-Item Checklist
What follows is the operational checklist the editorial desk runs against any new vendor before considering them for our ranking. Each item is binary: present or absent. Two or more "presents" on this list and we open a formal investigation. Three or more and we publish the vendor in the watchlist. Five or more and we add the vendor to the red-flag database directly without further courtesy.
The Checklist
- No physical address listed, or a listed address that geocodes to a mail-drop service.
- No registered business entity findable in the jurisdiction where the site claims to operate.
- No published Certificates of Analysis, or COAs that are not batch-specific.
- COAs that reference a lab that has no public verification mechanism or that we cannot reach independently.
- Pricing 30% or more below the established market floor for the same compound, with no plausible explanation.
- Aggressive bulk-discount structures ("buy 6 get 1 free", "20% off orders over $500") combined with crypto-only payment.
- "In-house testing only" or "tested for purity" without naming the testing lab.
- Telegram-only customer service, or any pattern of pushing customers off normal communication channels onto encrypted platforms.
- Pattern of unresolved customer complaints that we can verify independently — particularly reports of mass shortfall, sterile-issue concerns, or non-delivery.
- Vendor name reused across multiple domains with similar branding but inconsistent claims, suggesting a rotating-identity operation.
- Stock photography of "lab facilities" that reverse-image-search to other contexts.
- Claims of FDA, ISO, or pharmaceutical-grade certification that cannot be verified through the certifying body's own published records.
How To Run Each Check Yourself
Physical Address Verification
Take the address from the vendor's contact page and run it through Google Street View. Look at what is actually at that location. A legitimate manufacturer or distributor will have a building consistent with their claimed scale. A scam vendor will frequently list an address that geocodes to a UPS Store, a residential apartment, a coworking space, or — in our most documented case — a vacant lot in a different state from the registered business name. None of those rule out legitimate operation entirely; some legitimate small operators do work from home or from coworking spaces. But the combination of a residential or mail-drop address with high transaction volume and aggressive marketing is a strong fraud signal.
Business Entity Lookup
Every U.S. state publishes a Secretary of State business entity database. Free, public, online. Enter the claimed business name. Confirm registration status, registered agent, and date of formation. A site selling thousands of dollars per month of research compounds while operating as an unregistered entity is making a deliberate choice about regulatory exposure. International vendors should be checked against the equivalent registry in their claimed jurisdiction.
COA Verification
This is the single highest-value check. The two most-cited labs in the research-peptide ecosystem — Janoshik Analytical and Colmaric Analyticals — both publish independent verification channels. Janoshik provides a QR code on each COA that links to a verification page; if scanning the QR returns "not found" or a different result than the COA shows, the COA is fabricated. Colmaric will respond to direct email verification requests when given the COA identifier. We have personally verified that both labs respond to these requests within 1-3 business days. A vendor whose COA cannot be verified through the issuing lab's own channel is publishing a fabricated COA. There is no other plausible explanation.
Pricing Floor Analysis
The market floor for raw peptide synthesis at research scale is roughly knowable. For a fifteen-residue peptide like BPC-157, the cost of goods sold (synthesis, purification, lyophilization, vialing, labeling, shipping) is typically in the $8-15 per 5mg range when manufactured at moderate scale by a competent Chinese contract synthesis lab. Add markup, marketing, payment processing, returns, and customer service and the legitimate retail floor settles around $30-40 per 5mg. A vendor advertising BPC-157 5mg at $18 is either selling something other than what they claim, taking a sustained loss as a customer-acquisition tactic (rare in this market), or operating at a fraud-grade margin compression that cannot persist. The lower the price below the established floor, the higher the prior probability of fraud.
Customer Complaint Pattern Recognition
Reddit, Trustpilot, BodyBuilding.com forums, and several peptide-specific Discord servers accumulate user complaints. Read them. Look for patterns: not "this vendor was slow" (everyone is slow sometimes) but rather "I received vials of obviously different sizes" or "the powder didn't dissolve correctly" or "my package arrived with the labels wrong" or "I sent a sample to a lab and it came back at 60% of stated mass." Pattern-coherent technical complaints are signal. Isolated dissatisfaction is noise.
Two Cases We Will Not Name (But Will Describe)
Two vendors that came across our desk in the past eighteen months illustrate the checklist in action. We do not name them publicly here because both subsequently shut down their original brands and reopened under new names, making the public record more useful as a behavioral template than a specific accusation.
Vendor A presented as a U.S.-based research supplier with attractive pricing (approximately 25% below market floor) and a polished website. The physical address geocoded to a UPS Store in suburban Atlanta. The state Secretary of State business search returned no entity matching the claimed name. The COAs displayed were professionally formatted but referenced a lab whose website did not exist. Three of three checks failed. The vendor was added to the watchlist on the basis of the address and entity findings alone; the COA verification finding was confirmatory. Within four months the brand had shut down, and customer complaints about non-delivery and visibly under-mass vials accumulated on the standard community boards.
Vendor B was harder. The physical address was legitimate and resolved to a small commercial unit consistent with a small distribution operation. The entity was registered. The website displayed COAs that were correctly formatted with the Janoshik watermark. The check that broke the case was the COA verification: we submitted three of the displayed batch identifiers to Janoshik directly and received "not on file" for all three. Janoshik subsequently confirmed that the vendor was not a Janoshik customer. The COAs were fabrications using a watermark image grabbed from a real document. The vendor's response to our editorial inquiry was a legal threat. We published the finding anyway. The brand quietly disappeared within sixty days.
What Cannot Be Detected Pre-Purchase
The checklist will catch most outright scams before money changes hands. What it will not catch is the slower-developing fraud where a previously legitimate vendor shifts to substituted product without changing anything visible on their website. Catching that requires placing test orders and assaying the actual product — which is expensive enough that no individual consumer is going to do it for routine purchases. This is exactly the gap that an independent press is supposed to fill, and it is the gap this site exists to address. If you do want a vendor whose chemistry, shipping, and customer-service operation we have actually mystery-shopped end-to-end, the one supplier that held up across every dimension of that test is documented in the Honest Vendor Audit — the rest of the audited set is named there too, in the order they failed.

Editorial Standards
This report is updated periodically. Discrepancies between our reporting and reality are taken seriously — if you have observed something that contradicts what is published here, send it to the editorial desk with documentation and we will revise. Our reporting is constrained by what can be sourced, verified, or directly observed. Where evidence is weak we say so. Where it is absent we do not invent.
