Certificate of Analysis (COA) & Batch Disclosure
Batch disclosure policy
Given the pace and volume of operations at Lean Labs Peptides, individual batch Certificates of Analysis and testing updates aren't published to the website or emailed out for every production run.
Our inventory turns over frequently, and batch numbers, testing dates, and results are updated on a rolling basis. Publishing batch-specific documentation in real time isn't practical at that pace, and it risks circulating reports that are outdated, mismatched, or misapplied to the wrong lot.
Every product we distribute is tested by an independent third-party laboratory before release. Rather than leaning on static documentation, we back every product with a strict, purity-based efficacy guarantee — outlined below.
