State of Peptide Scams 2026: what 95 investigated sellers show
We investigated 95 peptide sellers and scored each one on a transparent 0 to 100 risk scale.
This is what the data says. How the gray market actually takes people's money, which signals predict a loss, and why a clean-looking storefront tells you almost nothing.
One thing first, because it frames everything below.
This is a documented-risk signal, not a quality grade.
A low score means we found few red flags in the sources we checked. It never means a seller is safe or fit for use.
The peptide gray market runs an estimated 5 to 10 billion dollars a year in the US. No product has FDA approval. There is no US-made active ingredient in the category, whatever a label says.
The numbers
95 sellers published.
83 carry a score. The other 12 are real vendors where public evidence was too thin to score honestly.
Risk bands, of the 83 scored:
- 🔴 19 high-risk (61 to 100). A documented pattern, usually a first-hand loss.
- 🟡 23 caution (40 to 60). Real gaps, no confirmed incident.
- 🟢 41 low (under 40). Few red flags. Not a clearance.
Median score: 40. Half the market has enough of a gap to warrant a second look.
Where they operate:
- China: 51
- Unknown: 28. Nearly a third cannot be tied to any real location or operator. That is a finding in itself.
- US: 11
- Europe: 4
- Canada: 1
The 5 patterns that cost people money
1. Advance-fee and non-delivery
19 files. The most common confirmed loss.
You pay, and nothing ships. Or "shipping" becomes escalating fees.
The documented losses:
- Zen Peptides, $1,131
- Aavant Research, $1,100+
- Kelly JEEP, $785
- JEEP Molly, $760
- Pure Peptides Lab, escalating post-payment fees
Two files scored a full 100/100. Each backed by more than one first-hand account.
2. Impersonation of a real brand
The most under-rated risk.
Scammers do not invent a vendor. They clone a trusted one.
The clearest case is the JEEP cluster.
A real-looking manufacturer whose name spawned impostors, to the point its own site now disowns them.
Same shape around Wuhan Wansheng (a fake clone site), jitai, and Laikang.
The rule: if a "rep" DMs you claiming a known brand, the brand is usually the bait.
3. Off-platform, crypto-only checkout
Vendors that push you off a card checkout into WhatsApp, Telegram, or Discord. Crypto or bank transfer only.
They cluster hard in the caution-and-up bands.
Card checkout is the one route with a chargeback.
Remove it and you remove your only recourse. That is why the higher-risk files keep showing it.
4. COA theater
A certificate of analysis should tie one batch to one lab test.
In the files, it is routinely faked or decoupled:
- Innopeptide: Janoshik COAs that are random, not your batch.
- HTRA: a batch number switched on the shipment.
- myPEPT: a retatrutide pen with no batch number at all.
- PeptiAtlas: vials that tested as pure filler.
- Shanghai ERP: underdosed, with high endotoxin, meaning contaminated.
A COA on the site is marketing until you match it to your own vial.
5. The legit-front, scam-DM trap
Some real, delivering vendors are safe to buy from but dangerous to talk to.
WBS is legit. A "Tiffany" who DMs you is not.
KeRui warns that Discord "KPB" contacts are 100% fake.
The vendor is real. The person contacting you is not. The loss happens in the side channel.
What the score can and cannot tell you
Every file runs the same rubric.
10 weighted factors: payment route, purchase protection, COA traceability, independent feedback, contact transparency, and more. Plus direct scoring for documented losses.
A score is provisional until 4+ factors are checked with one independently sourced. Then it is reviewed.
We write "no verified scam pattern found in the sources reviewed." Never "not a scammer."
A low score is honest, not reassuring.
Grey Axis Research is a named US LLC. But its COAs sit behind a login, so it stays flagged.
The number is where your diligence starts, not where it ends.
The buyer's short version
The strongest predictors of a loss:
- ❌ No card checkout
- ❌ Contact that moves to a DM
- ❌ A brand name a stranger "referred" you to
- ❌ A COA you cannot match to your own vial
Any two together should stop you.

FAQ
How many peptide sellers has Ouros Lab investigated?
95 are published with a public file, and 83 carry a numeric documented-risk score. The rest are real vendors where public evidence was too thin to score honestly.
What does a low scam score mean?
It means we found few red flags in the sources we reviewed. It is a documented-risk signal, not a statement that a seller is safe, legitimate, or fit for use, and never medical advice.
What is the biggest peptide-scam red flag?
The payment route. No card checkout, crypto or bank transfer only, and contact that moves to a DM are the signals most tied to a first-hand loss in the files.
Where does peptide scam data come from?
Each file is built from first-hand buyer reports, the seller's own surfaces, and public records, scored on a transparent 10-factor rubric. Methodology and every file are public.
