All peptides are supplied in a lyophilized (freeze-dried) powder form. This format improves stability by removing moisture and helps preserve structural integrity during storage and transport.
Lyophilized peptides can remain stable for extended periods—often 1–3 years—when stored at or below -20°C. After reconstitution, peptides are typically used within a shorter timeframe (commonly 7–30 days depending on storage conditions).
All products offered by Peer Research Services LLC are intended strictly for laboratory research purposes. They are not approved for human consumption, medical use, or diagnostic applications.

Peptides are short chains of amino acids linked together by peptide bonds. These structures are synthesized to precise sequences, which determine their properties and behavior in research environments.
Our peptides are supplied in a lyophilized (freeze-dried) powder form. This format improves stability by removing moisture and helps preserve structural integrity during storage.
Our focus is on providing peptides with an emphasis on purity and consistency. Lyophilized peptides are typically presented without unnecessary additives to support controlled research use.
Detailed product information, including storage recommendations and handling guidance, is provided on each product page.
Due to the nature of research compounds, returns are generally not accepted once products have been shipped. Please contact us if there are issues with your order.
