How pure are your research peptides?

All MMPeptides products are verified to 99%+ purity via HPLC analysis before dispatch. A Certificate of Analysis (COA) is available on request for every batch, confirming identity, purity, and molecular weight.

What peptides do you stock?

We stock a broad range of research peptides including BPC-157, TB-500, Retatrutide, Semax, Selank, DSIP, Melanotan I, Melanotan II, GHK-Cu, NAD+, Glutathione, and GLOW-80. All are supplied in lyophilised powder form with 99%+ HPLC-verified purity.

Are your products for human use?

No. All products sold by MMPeptides are supplied strictly for laboratory and analytical research purposes only. They are not intended for human or veterinary use. We do not provide dosage guidance or support human consumption in any form.

How do I store and reconstitute research peptides?

Lyophilised peptides should be stored at -20°C away from light and moisture until use. For reconstitution, use bacteriostatic water and add solvent slowly down the side of the vial — never shake. See our full Peptide Reconstitution and Storage Guide for detailed instructions.

What payment methods do you accept?

We accept Bank Transfer, Visa, and Mastercard. All transactions are handled securely. Bank transfer details are provided at checkout.

Can I get a Certificate of Analysis?

Yes. COAs are available on request for every product and batch. Contact us via our Contact page with your order number and we will send the relevant COA promptly.

Do you ship internationally?

Yes. We ship worldwide using DHL Express and Royal Mail International Tracked for fast, secure delivery. International orders are packaged with appropriate cold-chain considerations.

What is your returns policy?

Due to the nature of research-grade biochemical materials, all sales are final once dispatched. If your order arrives damaged, incomplete, or incorrect, contact us immediately and we will resolve the issue at no cost to you.
