PSPeptides

PSPeptides: Research peptides manufactured in the United States

PSPeptides is a US supplier of peptides intended exclusively for laboratory and in vitro research. The company produces its compounds in US facilities following current Good Manufacturing Practice (cGMP) guidelines and subjects every batch to independent testing for purity, heavy metals, endotoxins, and sterility. Its catalog is restricted to registered researchers and licensed laboratories; products are not intended for human or animal consumption.

Quality control and analytical transparency

The company maintains that no product self-certifies: all testing is performed by accredited third-party laboratories. Every batch is verified using high-performance liquid chromatography (HPLC) and mass spectrometry, with a minimum purity threshold of 99%. Certificates of analysis are available for every product, and reports for batches that are being shipped are published on the certifications page. The company states that if a peptide does not meet that purity standard, it will replace it at no cost.

Peptide and supply catalog

The catalog is organized by research areas and includes compounds such as Retatrutide, Tirzepatide, MOTS-C, Epitalon, SS-31, GHK-Cu, KLOW, and the BPC-157 + TB-500 combination. It also sells medical-grade bacteriostatic water (BAC) in 10 mL presentations and the PSPen device. The store also offers multi-peptide packs at a bundled price, including the bundles named “To Be Reborn,” “Turn Back Time,” “Repair & Renew,” “Cut & Glow,” “Gut Revival,” and “Shred Express.”

Shipping and logistics

Orders are processed the same day or the next business day; orders placed before 2 PM EST usually ship the same day. The company ships throughout the United States and its territories, and also to Canada, the European Union, the United Kingdom, and Australia. Shipping is free on any order, with free UPS 2nd Day Air shipping for orders over $200. Every shipment includes discreet packaging and full tracking via UPS or USPS, with email notifications at every stage of the journey.

Resources for researchers

The site provides users with a reconstitution calculator that allows them to obtain dosing volumes for any peptide, and a step-by-step video guide on mixing peptides. It also publishes research guides with dosing protocols and industry comparisons, including materials on Retatrutide, GHK-Cu, the BPC-157 + TB-500 combination, CJC-1295 with Ipamorelin, and a comparison between the GLOW and KLOW blends.
