A Certificate of Analysis is what should let you trust a powder you cannot see into. Paste one below — every field gets explained in plain English, scored against a transparency checklist, and, when we recognize the peptide, cross-checked against verified chemistry.
Analyzed on demand and never stored or logged.
Each transparency item present on the COA earns its weight; the score is the sum over the maximum. Grades: A ≥85% · B ≥70% · C ≥55% · D ≥40% · F below.
