Frequently Asked Questions
Everything you need to know about peptide research
What purity level are your peptides and how is it verified?
Every peptide is verified to ≥99% purity by HPLC. Each batch is analyzed by an ISO/IEC 17025-accredited third-party laboratory, and a batch-specific Certificate of Analysis is released with every product.
What is a Certificate of Analysis (CoA) and how do I read it?
A CoA documents a batch's identity, purity, net peptide content, and safety panel (heavy metals, sterility, endotoxin). It confirms the amount stated on the label matches what is in the vial.
What is Reconstitution Solution, for Laboratory Use?
Reconstitution Solution (for Laboratory Use) is used to reconstitute lyophilized (powder) research peptides. It contains a preservative that allows a reconstituted vial to be used over roughly 30 days when stored correctly.
How should I store the lyophilized product?
Store lyophilized (powder) peptides at ≤ −20 °C, where they remain stable for 24+ months. Once reconstituted, store at 2–8 °C and use within about 30 days.
How fast do you ship and is cold shipping required?
Orders placed before the daily cutoff ship the same day, with fast tracked shipping across the U.S. and overnight options available. Peptides ship with appropriate cold packaging to maintain stability.
Why should I trust Prestige Sciences?
