10-Point Panel Testing
Every PHAT batch goes through a full 10-point panel before it ships, with a certificate published for that exact batch.
If a batch shows any inconsistency, it is discarded and never listed.

Why PHAT
Forward, always.
The PHAT mark is an arrow for a reason. We built this brand for researchers who want to move forward with materials they can trust: clean data, honest pricing, no guesswork.
That is the standard behind every batch we test and every order we ship.
Our rule: if we would not put it on our own bench, it does not get a PHAT label.

Here to help
Questions, answered.
The short version of what researchers ask us most. Anything else, our team is a message away.
Peptides are short chains of amino acids, the same building blocks that make up proteins, only much shorter. Their sequence and length determine how they behave, which is why they are widely used as reference materials in laboratory research. Everything PHAT sells is supplied strictly as a research material.
Every product is intended solely for in-vitro and laboratory research. Nothing we sell is a drug, supplement, food or cosmetic, and nothing is intended for human or animal use. We do not provide dosing or administration guidance of any kind.
Yes. Each batch is tested by an independent third-party lab before it is listed, and the certificate for that exact batch is published on our COA page, free to read.
Orders paid before 2 PM CT, Monday to Friday ship the same day. Every parcel is packed discreetly and sent with tracking.
