Review of Certified

Review of Certified by Jordan Fisher
Finding a reputable company for sourcing research compounds can be difficult. The market is flooded with AI slop, fake COA’s, and what look like manufactured reviews. I actually came across Certified Peptides on accident through another company who previously did their purity testing, which I was purchasing my compounds through prior to knowing about Certified. That previous vendor was shut down for some less than savory business practices and I have been using Certified exclusively for the last year or so. The compounds are always of excellent quality their customer service is hands down, the best in the business. If they happen to be out of something I am looking for, I will wait for a restock and never consider trying to go elsewhere. Certified is that good. Prices are reasonable given the amount of compounds they carry and the testing they do, plus, while I know I can get 10x’s the amount for the price of a few vials from Certified via overseas vendors, I’ll continue to pay for the convenience of not needing to hassle with doing the testing myself. I have several coworkers doing their own research as well and they too only use Certified, so stop looking at other AI garbage companies selling who knows what with photoshopped COA’s and research with the best.
