Review of Certified

Review of Certified by Jos Roberto Gongora
I’ve had good experiences with Certified Peptides in the past, but my last couple of orders were disappointing. My most recent order arrived with several vial labels peeling or applied crooked, which didn’t inspire much confidence in their quality control. In a previous order, my GHK-Cu vial had no vacuum seal. About a week after reconstituting it, it started forming clumps and caused much more injection-site itching than I’d ever experienced with previous GHK-Cu cycles. I hope they tighten up their quality control because I’ve always wanted to keep buying from them.
