Independent lab checks · research peptide vendors
We order it. A lab tests it. You read the report.
Every vendor here was bought from anonymously, with our own money. The vials go to an independent lab, and the full report is published with a code you can verify yourself.
Method
How a vendor gets a score
An anonymous order
We buy like any customer would: retail price, our own card, a name the vendor doesn't know. No free samples, and no warning that a test is coming.
An independent lab
Sealed vials go to a third-party analytical lab for identity and purity testing. We photograph the lot numbers before they leave.
The whole report, published
The lab report goes up as issued, with its verification code, next to the vendor's own COA for the same lot. The score follows a fixed 100-point sheet.
Scorecards
Tested vendors
Sorted by total score. Open a vendor to see the lab reports, the order timeline and how each point was earned.
| Vendor | Score /100 | Lab purity | Vendor COA matched lab | Days to deliver | Last tested |
|---|---|---|---|---|---|
| Sample Vendor ASample | 87 | 99.1% | Yes, within 0.4 points | 3 | 2026-11-02 |
| Sample Vendor BSample | 74 | 97.8% | Yes, within 1.1 points | 5 | 2026-10-28 |
| Sample Vendor CSample | 52 | 93.4% | No, COA was for a different lot | 9 | 2026-10-21 |
These three rows are placeholders that show the layout. Real vendors appear here only after a completed test order and a published lab report.
The 100 points
What the score is made of
More than half the score comes from the lab bench and the paperwork. Nothing in it can be bought.
Ground rules
What we don't do
No paid placement
A vendor can't pay to be listed, to rank higher or to have a result removed.
No score without a test
If we haven't ordered it and had it tested, it doesn't get a number.
No dosing or health advice
These are research materials. We report purity, paperwork, shipping and service, and nothing about use in people.
No hidden commissions
Some links pay us a referral fee. Those pages say so, and the fee never changes a score.
