Prime Lab Peptides has solid basic disclosure and card checkout, with prices close to the market median. When we checked on October 19, 2026, it named PrimePeptide Laboratories Inc. in Miami, FL, published lot-referenced COAs and mentioned endotoxin testing. It doesn't name its testing lab, and we found no independent tests.
Notice: Prime Lab Peptides' products are sold for in-vitro laboratory research only. They are not FDA-approved and not for human or animal use. This review covers supplier transparency and prices. We didn't buy or test any products. Some vendors pay us a commission when you buy through our links. That never changes a score or a price ranking.

Testing and COAs
Prime Lab Peptides has a certificates of analysis page. The site mentions lot or batch numbers alongside its COAs and mentions endotoxin or sterility testing.
What's missing: no testing lab is named on the site, so you can't check a report with the lab. We also found no tests on Finnrick. The vendor's own COAs are the only quality evidence we could find.
What we like
- Named company and city.
- Lot-referenced COAs and endotoxin or sterility testing mentioned.
- Card payment, including Amex and Apple Pay. The site notes card checkout keeps your bank's chargeback rights.
- Tirzepatide, semaglutide, NAD+ and epitalon below the index median.
- Published FAQ, terms and refund pages.
What to watch
- No testing lab named.
- No Finnrick tests found.
- Every price is shown as a sale against a higher "was" price.
- Semax and selank are priced far above the median.
- Similar name to Prime Peptides, a separate vendor.
How it compares
Prime Lab Peptides is mid-priced, with better company disclosure than many vendors. See all vendors we track, peptide deals this week and our ranked list.
Bottom line
Prime Lab Peptides names its company, publishes lot-referenced COAs and takes cards. It doesn't name its lab and has no independent tests yet. Its prices are fair for the GLP-class compounds and high for semax and selank.
