PuroPeps – Premium Research Peptides – 99% Purity 3rd Party Tested

Q: Are your compounds third-party tested?

Yes — without exception. Every single batch is assayed by an ISO-17025 accredited independent laboratory before release. We test for purity, identity, sterility, endotoxins, and heavy-metal contamination. The certificate for your specific batch is available on request.

Q: What does the purity percentage actually mean?

Our purity figures come from HPLC (high-performance liquid chromatography) analysis, which measures the percentage of the target compound relative to impurities. A figure of 99.8% means 99.8% of the material is the verified peptide, with the remainder being trace synthesis byproducts well within pharmaceutical thresholds.

Q: How are orders shipped and stored?

All lyophilized peptides are stored in temperature-controlled GMP facilities and shipped same-day cold-chain when ordered before 2pm EST. Orders over $200 receive free insulated cold-chain shipping. We include reconstitution and storage guidance with every order.

Q: Do you provide reconstitution and dosing guidance?

Yes. Every order includes reconstitution and storage guidance for laboratory handling, including Research Water ratios.

Q: Is there a satisfaction or quality guarantee?

If any product arrives compromised, or a COA cannot be matched to your batch, we replace it or refund it — no questions asked.

Q: Who can purchase from PuroPeps?

Products are sold strictly for laboratory and research use by qualified individuals aged 21 and over. They are not intended for human consumption. By completing a purchase you confirm you meet these requirements.
