We’re putting peptide brands on trial.
The label tells you almost nothing. So we buy the brands people actually use — anonymously, like any customer — send them to an independent lab, and publish what comes back. Pass, mixed, or fail.

Five questions a label can’t answer
Every trial grades a brand on the same five things — and, just as importantly, says what each result doesn’t prove.
Identity
Whether the vial actually contains the peptide named on the label — the right molecule, not a look-alike or a substitute.
What it doesn’t prove: It can't confirm every trace compound present, only that the labeled peptide is (or isn't) the primary content.
Purity
How much of the contents is the intended peptide versus fragments, byproducts, or other impurities — usually reported as a percentage.
What it doesn’t prove: A high purity number says nothing about sterility or whether the dose matches the label.
Potency & dose accuracy
Whether the amount in the vial matches the milligrams claimed on the label — so your mixing math reflects reality.
What it doesn’t prove: It reflects the specific vial(s) tested; it can't guarantee every unit in every batch is identical.
Sterility & endotoxin
Whether the product is free of microbial contamination and bacterial endotoxin — the things that make an injectable unsafe regardless of purity.
What it doesn’t prove: Sterility at test time can't account for how a product is handled, reconstituted, or stored after it reaches you.
Transparency
Whether the brand publishes its own third-party testing (a Certificate of Analysis) and whether those claims hold up against an independent test.
What it doesn’t prove: A published CoA is a good sign, not proof — which is exactly why we test independently instead of taking it on faith.
Blind, independent, and published as-is
The integrity lives in the process. Brands don’t pay to be tested, don’t pick the vial, and don’t get to approve the result.
- 01
Nominated
Brands enter the queue from community nominations and from what people are actually buying — not from anyone paying to be tested.
- 02
Acquired blind
We buy the product anonymously through ordinary retail channels, like any customer would. The brand doesn't get to hand-pick the vial we test.
- 03
Tested independently
Samples go to an independent, third-party analytical lab. WikiPeps doesn't run the assays — we commission them, so the numbers aren't ours to shade.
- 04
Published unedited
Results are posted here as-is — pass, mixed, or fail — with the methodology attached. Brands don't get to approve, spin, or bury a result.
- 05
Re-tested over time
A single vial is a snapshot, not a guarantee. Brands get re-tested so a one-time pass can't stand in for consistency.
Verdicts as they land
Each brand shows where it is in the pipeline. Published verdicts link to the full breakdown and methodology.

Four possible outcomes
The tested vials met the labeled identity, purity, and dose within tolerance, with no sterility or endotoxin red flags.
Some results checked out and others didn't — e.g. correct identity but off-target dose, or good purity but no published testing.
One or more core results came back wrong — misidentified, badly under- or over-dosed, or contaminated.
Not yet run. The brand is queued or currently in the lab — no verdict has been earned yet.
How to read these results — honestly.
A trial reflects the specific vials we tested, at the time we tested them. It is a strong signal, not a guarantee: a batch can change, and a pass is not a recommendation to buy or use anything. Dose Labs does not sell, supply, or source peptides — we acquire products anonymously through ordinary retail channels solely to test them, and we publish results whether a brand likes them or not. Everything here is educational and is not medical advice.
