About Sequence
The lab reports are
part of the product.
Sequence was founded in Los Angeles with a simple observation: the peptide market is full of companies that look like they have something to hide. Sketchy websites, vague sourcing, no verifiable lab data.
Every product ships with a certificate of analysis you can download before you buy — HPLC purity confirmation, mass spectrometry identity verification, batch number. The science doesn't change; the paper trail proves it.
Our peptides are sold for research purposes. We don't make medical claims and we won't. What we will do: publish every lab report, label every vial accurately, and ship every order cold. You'll always know exactly what you bought and what the independent lab said about it.
