"The BPC-157 consistently delivers 99%+ purity. I've benchmarked four suppliers — Gold Standard's CoA matches the independent results I run in-house. That level of transparency is genuinely rare in this space, and it has made this our lab's default source for every peptide we use."

Cold-chain arrived intact. Mass spec data matched our in-house verification to within 0.2%. We've since switched our entire research group's peptide procurement to Gold Standard.

GSP is the only supplier I've found that treats documentation with the same rigour applied to the synthesis itself. The batch traceability system is exactly what reproducible research demands.

Purity measurably higher batch-to-batch, documentation flawless, and the scientific support team understands the compounds mechanistically. Switched six months ago — we will not be going back.

No. All compounds sold by Gold Standard Peptides are strictly for laboratory and in-vitro research use only. They are not approved for human or veterinary use, and are not intended for any clinical or therapeutic application. Our products comply with applicable regulations regarding research chemicals.
Every product page includes a downloadable CoA for the current batch. Upon order, the batch-specific CoA is also accessible directly from your account order history. The CoA includes HPLC purity percentage, mass spectrometry data, molecular weight confirmation, and moisture content.
We offer standard and expedited shipping with full tracking. Peptides ship lyophilized (freeze-dried) in sealed vials inside discreet, temperature-controlled packaging. Temperature-sensitive compounds are shipped with dry ice or cold packs. Most orders dispatch within 24 hours of payment confirmation.
Our minimum purity threshold for any compound to be released for sale is 98% as measured by HPLC. The vast majority of our catalog exceeds 99% purity. Batches falling below 99% are re-synthesized or discarded. Independent mass spectrometry confirms compound identity on every batch.
Yes. We offer institutional and volume pricing for academic labs, research organizations, and CROs with verifiable research credentials. Contact our team at abservicesx@gmail.com with your institution details and compound requirements for a custom quote.
Lyophilized peptides should be stored at -20°C for long-term stability (up to 24 months). Once reconstituted, store at 4°C and use within 4 weeks. Avoid repeated freeze-thaw cycles. Keep away from light. Specific storage recommendations are included on each product's datasheet.
