I’ve purchased from them several times this year… never been disappointed by their product. Very clean results. Ships FAST out of the KC area. COA’s seem solid (they currently use Kovera-Labs & MZ-BioLabs). PeptideCritic coupon-code is better than advertised. They’re NOT the most affordable, but if you just wanna research a few vials of several different compounds… it’s a good starting place. Hopefully they get a rewards-program to retain customers.
