Independently tested, every single batch
Peptides you can actually verify
Peptidesfarma supplies United States research labs with high purity compounds. Every lot is analysed by an outside laboratory and the full certificate is published before you are asked to buy anything.
Why we exist
Buying research material had turned into an act of faith. Purity figures with nothing behind them, batch numbers that went nowhere, and a certificate only after you had paid.
A purity number that cannot be checked is marketing copy, not data.
So we inverted it. The lab tests first, and the certificate is published while you are still deciding.
How we verify
Quality you can verify, not just trust
Every batch is independently tested by an accredited U.S. laboratory. We publish the certificate for the exact lot in your vial, so you can read the real numbers before you buy.

The lab has a name
Every certificate names the accredited lab that ran it and links to the lab's own verification portal, not a page we control.

Matched to your lot
Verification is batch level. The lot printed on your vial matches the lot on the certificate, down to the number.
03
