Composite score
BioTech Peptides
76/100Established 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.

74/100Aggressively-priced US-based vendor that carries the full GLP-1 mainstream — Retatrutide, Tirzepatide, and Semaglutide all in one catalog. Public-facing brand "Prime Research Peptides" appears to be a storefront for Truform Compounds (same parent company, confirmed via about page). Strong on price, weak on public COA surface — testing is claimed but documents aren't published.
