I think i began ordering from them a couple months ago. A couple months before I used this company I used another company. And looking back I remember it was like pulling teeth to get info on peptides. And it was so inconvenient, I had to email them and wait up to a day or so to get a reply. And they never gave direct answers nor did they offer protocol sheets per peptide. I feel spoiled with certified peps because I get on the spot answers to my immediate questions 24/7, its lije they don't sleep. I feel like they give honest opinions and are defiantly not ones to upscale peptides. I have not looked into other companies since CertPep meets all my needs. I feel 100% confident in the research they put into their peptides. Amazing is all I can say & brilliant customer service!
