I’ve ordered from certified peptides 5 or 6 times and have been very happy with the products. Everything comes well packed and it seems customer service is available when needed…..I’ve not needed customer service yet. More importantly I’m seeing the results of the products which solidifies the quality. I will continue to order from them.

I just think the product works really well and the price is extremely reasonable. I use to by the very same product from an esthetic clinic and pay about $175 more! However when I got my product I was unaware I needed BAC water to mix it
