These guys are fantastic. They always available on the chat app with helpful info and direction. I have learned so much. I have placed several orders and the last one they upgraded the shipping to 2 day as I live in AZ and it has been 115. Who does that? Certified Pep does!! I look forward to shopping and learning in the future. Buy with confidence. They will never let you down!

Waited for some friends to order first, you know the gray market trust thing. Well I researched, asked questions, and ordered. Shipping is fast, like 4 days fast and I am in wisconsin. This is my first order see progress we will see. I previously visited a mens health clinic that prescribes peptides for 3 times the price, and got really good relief for my shoulder pain. we shall see.
