How to spot a peptide scam.

No vendor is flagged here without documented, verifiable evidence and a right of reply. Below: the five red flags you can spot yourself, and exactly how our flagging works. Scam Watch is never for sale.

5 red flags of a peptide scam

  1. No lab paperwork. A real vendor shows a Certificate of Analysis (COA) for the exact batch you are buying.
  2. A price that is too good to be true. Compare it to our price index — far below the range usually means fake or underfilled.
  3. Pressure to buy. Countdown timers, “only 2 left,” or sales only by direct message are tactics, not deals.
  4. Odd payment. Gift cards, wire-only, or crypto-only — and anyone asking for a password — are hard stops.
  5. The same “lab report” on every product. That is decoration, not testing. Each batch should have its own.

Your first vendor safety-check, one step at a time

Slow and plain. Five steps, one thing to do at each. This tells you whether a vendor is being honest — not whether to buy or use anything. For research use only.

1

Find the vendor in our directory

Search our vendor directory for the seller. Note their Trust Score. Not listed at all? That alone is a reason to be careful.

2

Look for a COA on the vendor’s own site

A Certificate of Analysis is the lab report for a batch. If the vendor publishes no COAs anywhere, stop here — that is the single biggest red flag.

3

Check the COA has a batch number that matches

The COA should show a lot / batch number, and it should match the product you are looking at. One generic “lab report” reused on every product is decoration, not testing.

Compare the price to our index

Find the compound in our price index. A price dramatically below the range is a warning, not a bargain — it usually means fake or underfilled, not generosity.

Check Scam Watch

Last, see whether the vendor appears on Scam Watch, and read the 5 red flags above so you can spot the tactics yourself.

Remember: none of these steps tells you whether to buy or use anything — that is a separate, personal decision. They only tell you whether a vendor is being honest. For anything about your own health, talk to a licensed clinician.

No public flags yet. Scam Watch launched in July 2026. A vendor is flagged here only on documented, verifiable evidence — a failed lab result, a reused COA, or a confirmed pattern of non-delivery — and every vendor gets a right of reply before a flag goes live. When the first flags are published, each will link to its evidence.

How flagging works

Evidence first. A flag requires documented proof — a failed lab result, a reused COA, or a pattern of non-delivery. We don’t flag on rumor.
Right of reply. Every vendor is contacted before a flag goes live and can respond or correct the record.
Correctable. Flags are removed when the issue is genuinely resolved — see “Cleared.” A flag is a documented finding, not a permanent verdict.
Neutral. Being flagged is never influenced by whether a vendor pays for anything.

Seen something off?

Send us a bad COA, a counterfeit, or a non-delivery report. Tips are reviewed before anything is published.
