It lists 58 products, including Tirzepatide, Retatrutide, BPC-157, GHK-Cu, TB-500, and MOTS-c, plus 28 other compounds. It also produces and labels to order, so stock sold under other brand names may come from here.
In its own words: “SSR Bio is a specialized supplier of research peptides and biochemical materials, serving partners worldwide.”
SSR Bio publishes 28 certificates of analysis on its site, all credited to Janoshik Analytical. The vendor chose which batches to publish, so those results do not tell you what is in the vial you receive. Of the 12 product pages we opened, every one links its own certificate.
