55/100Operator 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.
