From start to finish, or purchase to delivery, certified peptides made the entire process super. The delivery only took about 4 days,with a tracking number to check on your products. Each delivery is packed extremely well. I am so glad I can put my trust in certified peptides.

"I've been using Certified Peptides for Retatrutide and a few mimetic HGH products like CJC-1295 and Ipamorelin. I don't have a lab to confirm quality but based on my 3-months of experience with the company, their ""for testing purposes only"" products seem to be legit. Especially the RETA product - it clearly works and seems to be from a good source. They're somewhat local to me (WA State) and I'm confident that they'll make me whole if there's ever a problem. There are several good peptide labs; this is one of them."

This company provides excellent quality peptides at a fair market price. With all the quality issues currently affecting suppliers, you can always count on certified peptides to deliver the real thing at the right dosage every time! Couldn’t be happier with Jason and his team!

Love this company, the customer service is top tier, all peptide are amazing currently using SNAP8, NAD+, GLOW and Tirzepatide, will be ordering many more times in the near future. The $100 minimum order gets me sometimes, but it's a small price to pay for great products!

Your customer service is exceptional however, I am a little concerned that the product is not working properly for me. I need to reach out to one of your personnel to see if I am using it properly. I am up for re-ordering right now thank you.
