VENDOR AUDIT
Summit Biotech
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.
