PX1 Research peptides are manufactured, lyophilized, tested and packaged entirely in GMP-compliant United States facilities. 100% domestic manufacturing, packaging and shipping — no imported material, ever.
Every PX1 peptide starts and finishes in the USA. We control manufacturing, purification, lyophilization, vial filling and packaging domestically, so there is a documented American chain of custody from raw amino acids to sealed vial.
That means no customs delays, no re-labeled overseas peptide, and consistent, verifiable lot-to-lot quality.
Production runs in GMP-compliant U.S. facilities under documented batch records and quality controls, giving clinics and labs the paper trail they need to qualify PX1 as a supplier.
Every lot is independently tested by an ISO 17025-accredited lab for identity and purity, with HPLC and mass-spec COAs available on request.
Are PX1 peptides really made in the USA?
Yes — 100% manufactured, packaged and shipped domestically in GMP-compliant U.S. facilities. We never import and re-label.
Do you import any peptide material?
No. Our supply chain is fully domestic end to end.
All products are sold strictly for laboratory and research use only. Not for human or veterinary use, diagnosis, treatment or consumption. Statements have not been evaluated by the FDA.
