I want to tell everyone how exceptional and fabulous this company is! Jason was more than accommodating and helpful to me! I just can't say enough good things about him! Ordering was easy, delivery was fast, I will be sticking with this company for my Peptides. Right now, just the Reta, but looking at others. I was on Tirz for 2 months, but the cost was becoming prohibitive. If you are on the fence, order from Certified Peptides today!!
