§ 01

Composite score

biotech-peptides

BioTech Peptides

76/100

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.

vs
summit-biotech

Summit Biotech

55/100

Operator received an FDA warning letter on December 10, 2024 as "Summit Research Peptides," then rebranded to Summit Biotech without disclosing the prior identity on the new site. Login-walled catalog, code-name SKUs for the FDA-cited compounds, and the cheapest per-mg pricing in our seven-vendor index on Tirzepatide, Retatrutide, and Semaglutide. ~90% of COAs are real Janoshik public-database links.
