Know how far you can trust where your peptide came from.
PepCheck asks a few plain questions about where a peptide came from and who supervised it, checks the source against a registry of accredited facilities, and gives you a letter grade with exactly what would raise it.

About two minutes, start to finish.
- 1
Identify the peptide
Scan the code on the label, or type the peptide name and lot number. Anything the app reads is shown back to you to confirm.
- 2
Answer a few questions
Where you got it, whether your name and a prescription are on the label, whether a licensed provider evaluated you and ran baseline labs, and what the packaging says.
- 3
Name the source
Search a registry of FDA-registered outsourcing facilities and accredited compounding pharmacies, or skip the step.
- 4
Get your grade
One letter from A to F, the reason behind it, and concrete steps that would raise it.
Two questions. The weaker answer sets the grade.
Product quality asks how accountable the source is: a prescription in your name, an accredited facility, a certificate of analysis for your lot, and no “research use only” label.
Clinical oversight asks whether anyone is actually supervising: a licensed provider who evaluated you and ran baseline labs before prescribing.
Inferred is not verified.
It grades the story behind the vial, never the vial itself.
It does not test the vial
There is no lab. Nothing is chemically analysed.
It is not medical advice
It never tells anyone to use or not use a peptide.
It is not a safety clearance
An A means well sourced and well supervised, not safe.
It endorses no product
It grades provenance and oversight, nothing else.
Pharmacy licensing is public information. Your state board of pharmacy is the authoritative record of whether a pharmacy is licensed and in good standing.
Check your peptide.
Built by the American Academy of Peptide Medicine for patients and clinicians. A prescribed, supervised peptide from an accredited pharmacy grades well, and the app says so.
