About PeptideReceipts

The research-peptide market runs on trust it hasn't earned. We exist to fix that — by teaching you to verify what's in the vial instead of taking anyone's word for it.

Why this site exists

Research peptides are sold with no FDA oversight, into a market with a long history of exit scams, underdosed vials, and outright fakes. The single objective fact in that whole mess is the third-party certificate of analysis (COA) — the lab document that says what a compound actually is and how pure it is. Almost nobody teaches people to read it.

That's the gap. Receipts over reviews. Learn to read the document, and you stop being a target.

What we cover

  • How to read a COA — identity (mass spec), purity (HPLC), and the chromatogram
  • How to spot a forged, recycled, or batch-mismatched COA
  • Vendor verification — what real transparency looks like vs. a "lab-tested ✓" badge
  • Reconstitution and handling math, explained plainly (educational, not a protocol)
  • The science behind common research compounds — with honest uncertainty, no hype

Our standards

We show the document. Claims without a verifiable source are marketing, and we say so.

We make no therapeutic claims. Everything here is research/educational (RUO). We explain how to evaluate evidence and documents — not what to put in your body.

We disclose, because a transparency site that hides its own ties is a joke.

Honest disclosure

PeptideReceipts is published by the team behind Peptides Optimized, a vendor that publishes a third-party COA for every batch it carries — the exact standard this site argues for. We point to vendors that meet that bar, Peptides Optimized included, and some links may earn a commission at no extra cost to you. That relationship doesn't change the standard — the whole point is that you can check the receipts yourself rather than trust us.
