How to read a peptide certificate of analysis
Purity, identity, endotoxin, residual solvents — what each number on a peptide COA actually proves, and the four fields to check before you trust it.
ReferenceThe five research categories, and what distinguishes them
Recovery, growth, metabolic, longevity and tanning — how the catalogue is organised, which receptor families each category maps to, and where the overlaps are.
