Lipeptides Safety Rating & Test Results

As of 9 Aug 2026, Finnrick has published 48 independent lab tests of 5 peptides from Lipeptides: 38 passed, 9 failed, and 1 was not classifiable (incomplete data) under the default public standard, Purity Focus (HPLC purity at least 99.5%, fill within ±35% of the label claim). The latest test is dated 5 Aug 2026.

Finnrick ratings are recency-weighted pass percentages: newer tests count more, and vendors with thin test histories are pulled toward the peer baseline for that peptide, so a single result cannot look too certain. Samples are analyzed by independent partner laboratories and the results are published by Finnrick Analytics, which does not sell peptides and does not accept payment to alter ratings. Corrections to published data are recorded at finnrick.com/corrections.
