Testing & traceability
The report should match the vial.
Documentation is only useful when it refers to the exact batch in front of you. Every listing carries a batch reference, and the record held for that batch uses the same fields in the same order — identity, purity, method and report reference.
We describe what the documentation contains and how it is produced. We do not make claims beyond what the record itself states.

Approach
Why The Peptide Guys
01
Documentation
Each listing links to the documentation held for its batch, in a consistent format.
02
Traceability
Batch references connect the label, the listing and the record for that batch.
03
Simplicity
Plain specifications and no unnecessary detail between you and the information you need.
