Frequently Asked Questions

What are research peptides?
Research peptides are short chains of amino acids supplied strictly as reference materials for in-vitro and laboratory research. They are not intended for human or veterinary use, consumption, diagnosis or treatment.
Are your research peptides third-party tested?
Yes. Every batch is independently third-party tested to at least 98% purity by HPLC and ships with a certificate of analysis (COA). All products are USA-made.
What does research use only mean?
Research use only means the product is sold exclusively for laboratory and research purposes. It is not a drug or a supplement and is not intended for human or animal consumption.
Do you offer wholesale or bulk pricing?
Yes. We offer wholesale and bulk pricing, with quantity discounts shown on the product pages. For larger bulk research quantities, see our wholesale and bulk pricing page or contact us by email.
Do you ship across the US?
Yes. Peptides Source is US-based and ships domestically across the United States.
How should research peptides be stored?
Most lyophilized (freeze-dried) research peptides are stored frozen while sealed; once reconstituted in the laboratory they are kept refrigerated and protected from light. Oral formats are kept in a cool, dry place. Always follow the handling notes on each product page.
