Every peptide in the Peptidos collection meets or exceeds 99% purity standard, confirmed through independent third-party analysis. Each product is provided with a certificate of analysis for the batch.

We publish lab reports on our website for full transparency.

Generally for optimal stability:

• Keep vials in a cool, dry place, ideally in a refrigerator (0–8 °C) or freezer (–°C) for long-term storage.
• Once reconstituted, peptides should be used promptly and kept refrigerated.
• Avoid repeated freeze-thaw cycles to preserve quality

Yes - all Peptidos vials are lyophilized (freeze-dried) to ensure maximum stability, purity, and shelf life.

This process preserves peptide integrity during shipping and long-term storage by protecting the molecules from heat, moisture, and oxidation.

Due to the nature of our products, all sales are final - items are non-returnable once shipped.

However, if you receive a damaged, defective, or incorrect product, please contact our support team within 7 days of delivery. We’ll review the case and arrange a replacement where applicable.
