Cernum Biosciences is a live store with above-median prices and basic purity reports. As of October 19, 2026, it lists 22 peptides with public prices. It posts per-product purity reports, but we found no named labs, company details or Finnrick tests.
Notice: Cernum Biosciences' 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 only. 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
The site's Purity Testing page lists the catalog and opens a report for each product (rechecked October 20, 2026; our first pass on October 19 missed it). The page doesn't name the lab or tie reports to lot numbers, so check the lot on the PDF against your vial. We found no Finnrick tests.
What we like
- Public prices with no gate.
- A purity report for each product on its testing page.
- GHK-Cu and the BPC-157/TB-500 blend below the index median.
What to watch
- Reports aren't tied to lot numbers on the page, and no Finnrick tests.
- No company name or address published.
- Most prices above the median; many items out of stock.

Bottom line
Cernum Biosciences charges more than most vendors we track and shows less testing detail than most. Vendors with lot-matched COAs are easier to verify.
