Wholesale Peptides, Made in the USA
PX1 is a US peptide manufacturer supplying bulk and wholesale peptides direct from the lab — we're one of the very few companies actually synthesizing peptides on US soil, not repackaging imported powder. Every compound is built from the ground up in a cGMP lab, verified by HPLC and mass spectrometry, and screened for endotoxins through an ISO/IEC 17025:2017 accredited laboratory. Bulk pricing, private-label and custom batch sizes for brands, clinics and resellers.
We probably already supply your favorite brand.
Many of the peptide brands you already know and trust source from us or our manufacture — they just put their own label on it. Skip the middleman markup and buy direct from the lab that synthesizes it.
