Every product sold by NAPS Peptides is tested to a minimum of 99% purity using reverse-phase HPLC. Batches below this threshold are rejected and never released.

How are your products tested?

Our standard protocol includes reverse-phase HPLC for purity, mass spectrometry for structural identity, and endotoxin screening where applicable. Testing is performed by independent third-party laboratories.

Can I request a Certificate of Analysis?

Storage & Handling

How should I store peptides before reconstitution?

Lyophilized peptides should be stored at minus 20 degrees Celsius (standard freezer). Most compounds remain stable for 12 to 24 months when stored properly.

How long are reconstituted peptides stable?

Most reconstituted peptides remain stable at 2 to 8 degrees Celsius (refrigerator) for 14 to 30 days. Refer to the product page or contact us for compound-specific stability.

What should I reconstitute with?

Bacteriostatic water is the standard reconstitution solvent for most research peptides. We stock it in our Supplements category.
