Testing: Labs & Certificates of Analysis

Limitless Biotech links its certificates from the COA tab on each product page. Prof. Peptide counted 304 distinct certificate files across 51 product pages on 9 October 2026, from TrustPointe Analytics, Janoshik, MZ Biolabs and Vanguard Laboratory. Limitless Biotech states that its premium lyophilized products are verified at 99% purity or higher, with each batch tested for purity, endotoxin and sterility.

The TrustPointe certificates, the largest group, were checked at TrustPointe's own verification on 9 October 2026, after it refused an invented key, and each one drawn matched the lab's record byte for byte. Each TrustPointe certificate covers one test, such as endotoxin or sterility, for a numbered lot.

Finnrick rates Limitless Life Nootropics 54% across 22 tests (read 9 October 2026) — a pass rate across those tests, weighted so that newer tests count for more, not a purity figure.

All products are sold for laboratory research use only.
