Frequently asked questions

What is peptime.com?

What are peptides?

Peptides are short chains of amino acids that function as signaling molecules in experimental biological models. In laboratory research, they're extensively investigated for their interactions with cellular pathways, such as those in metabolism or tissue models. Learn more about specific peptides in our product descriptions.

Are Peptime peptides tested for purity?

Yes, every batch is rigorously tested by independent US-based third-party labs to confirm identity, purity (≥99%), and quality via HPLC and MS analysis. Batch-specific Certificates of Analysis (COAs), including detailed reports, are available upon request or downloadable for verified researchers. This commitment to transparency ensures reliability for your lab experiments—all strictly RUO, not for human use. Contact us if you need a sample COA.

What does “Research Use Only (RUO)” mean?

"Research Use Only (RUO)" indicates that products are designed exclusively for in vitro laboratory research or approved animal model studies. Per FDA guidelines, Peptime's RUO peptides are not evaluated or approved for diagnostic, therapeutic, clinical, or any human/animal consumption purposes. By purchasing, you confirm use solely for qualified scientific research. Visit our terms for full details.
