Two audits, side by side. Composite, subscores, shipping, payment, coupons. BioTech Peptides takes the higher composite this cycle.
Established US-domestic peptide synthesizer with a substantial catalog and same-day shipping. COA practices are the open question — testing is claimed in marketing copy but not surfaced on product pages or a public lab-results route. Public-data preview; first-hand audit pending.
US shop on an 18-month-old domain that publishes 157 certificates across 82 compounds from two independent labs, Freedom Diagnostics and Kovera, with a verification code on each. None of it is in our independent mirrors, the purity figures are the labs' as published by the shop, and retatrutide sells behind the code name "GLP3-RT". Public-data audit, no first-hand order, 62/100.
