All profiles
American Peptides makes unusually broad company-wide testing claims and backs them with a large public COA library in which superseded lots are explicitly marked rather than removed. Product-level review confirmed nine current lots covering every check in this review, including sterility.
Documented strengths
- ✓States that every lot of every compound passes seven checkpoints: MS identity, HPLC purity, net peptide content, endotoxin, sterility/microbial, ICP-MS heavy metals and an independent third-party COA.
- ✓COA library lists more than 50 products and many multiple or superseded lots, including Retatrutide, Tirzepatide, BPC-157, GHK-Cu, SS-31, TB-500, Tesamorelin and a BPC/TB blend.
- ✓Older reports are marked superseded rather than simply disappearing.
- ✓Nine current lots reviewed at product level carried heavy metals, endotoxin, sterility, HPLC purity, measured quantity and lot traceability.
Limitations in this review
- —Indexed product pages emphasize HPLC/MS, with the deeper panels living inside the lot reports.
