About Certified Peptides
Certified Peptides is a U.S. research peptide store. We sell 126 products, all made in the USA and tested batch by batch by an independent U.S. laboratory.
Who we are at Certified Peptides
We started Certified Peptides with one rule: only sell U.S.-made peptides and show the testing behind them. That’s where the name comes from. Every batch has a lab report, and on most products you’ll find it in the photo gallery, next to the vial.
The range covers GLP-1 peptides such as GLP3-R (retatrutide) and GLP2-T (tirzepatide), healing and recovery peptides such as BPC-157 and TB-500, growth hormone peptides, anti-aging peptides, capsules, lipotropic blends and the lab supplies to go with them.
How Certified Peptides tests every batch
An independent U.S. lab confirms identity by mass spectrometry, measures the content and checks purity by high-performance liquid chromatography (HPLC). Our standard is 99% or higher. The lab also screens for endotoxins, heavy metals and sterility, because a pure peptide with endotoxin in it can still ruin a cell study.
You can read more on our lab testing page, or go straight to a product, such as the BPC-157 TB-500 blend, and open the lab report from its gallery.

Why buy direct from Certified Peptides
Buying from us means the batch on your label is the batch on the report. We don’t relabel other people’s stock, and we don’t sell through marketplaces. If you see our name somewhere else, check that the link points to this site.
Prices are listed in U.S. dollars on every product page, and 41 products are on sale right now. Bigger vials cost less per milligram, and each product page shows the other sizes with the price per milligram, so comparing takes seconds.
What we ask of our customers
Everything we sell is for laboratory research only. It isn’t for human or veterinary use, and we don’t give dosing advice. Our product pages stick to what the compound is, what published studies found, how to store it and how to reconstitute it.
