It’s common practice in the industry to work with multiple testing labs, and this approach supports transparency and accuracy. In this instance, Purilabs offered the site administrator a free blind test with a lab of his choice to demonstrate credibility, but he declined and proceeded to post critical remarks after I questioned his assertion that our lab partner was “questionable at best.” Furthermore, criticism regarding our website’s user-friendliness was cited as a reason for denying our vendor listing, which I believe is unrelated to product quality or verification.
For additional context, Lost Coast Aminos documented on social media that they submitted three of their peptides to Purilabs for testing, having previously verified these with another trusted lab. The results from Purilabs were consistent with their past lab's findings, reinforcing the reliability of the testing process.
Using more than one lab and maintaining selective publishing standards—such as only sharing Purilabs results when they align with the COAs from our vendors—are practices intended to ensure quality, not to appear misleading. Notably, the owner of Lost Coast Aminos has also stated an intention to migrate all their testing to Purilabs once necessary references are in place. https://www.tiktok.com/@lostcoastaminos4/video/7698086457130437901?_r=1&_t=ZP-9AfmL56cnMt
