Genesis Peptides: Independent Lab Review (111 COAs Tested)

TitrateLab tracks 111 third-party lab certificates of analysis for Genesis Peptides, averaging 99.6% tested purity across 105 assayed batches, with 98% of those batches in spec on both purity (≥90%) and labeled dose (filled to within 10% of the labeled amount); 2 assayed batches were significantly underdosed (worst -15% vs the labeled amount) (tests dated 2025-08-01 to 2026-06-30). These are purity analytics from independent certificates, not vendor marketing — TitrateLab does not rank or endorse vendors, and this is research-use-only information, not a recommendation to purchase or use any product.

Across the 105 assayed batches TitrateLab tracks for Genesis Peptides, the mean third-party-tested purity is 99.6%. Purity is measured on the specific batches that were submitted for analysis and is not a guarantee for any other lot.

TitrateLab tracks 111 published third-party certificates of analysis for Genesis Peptides spanning 32 distinct compounds. Each certificate links to its own public page with the purity, test method, issuing lab, and test date.

98% of the 105 assayed batches TitrateLab tracks for Genesis Peptides (103 of 105) were in spec on BOTH tested purity (at or above 90%) and labeled dose (filled to within 10% of the labeled amount). 2 assayed batches were significantly underdosed against the label (worst -15%), so they are counted as out of spec even where tested purity was high. This reflects only the batches that were tested and is analytic information for research use, not a quality guarantee for any order.
