Currently we ship within the United States only.
How should I store my peptides?
Lyophilized (powder) form: store at −20°C for long-term storage, or 2–8°C for short-term. Once reconstituted, store at 2–8°C and use within 1–3 months depending on conditions. Always protect from light and avoid repeated freeze-thaw cycles.
What is the shelf life of your peptides?
Lyophilized peptides have a shelf life of 2+ years when stored properly at −20°C. Each product includes a lot-specific expiration date.
What is the purity of your peptides?
All compounds are manufactured to 99%+ purity standards. Each batch undergoes third-party HPLC and mass spectrometry testing. A lot-specific Certificate of Analysis (CoA) is available on every product page.
Are your peptides third-party tested?
Yes. Every batch is tested by independent, accredited laboratories using HPLC for purity verification and mass spectrometry for identity confirmation. Results are published on each product page as Certificates of Analysis.
How do I access Certificates of Analysis?
CoAs are available on each product page — view or download the current batch’s results directly. You can also look up your specific product’s lot from the code on the vial, or request a CoA by emailing
help@mydoseone.com with your order number.
Where are your peptides manufactured?
Our research peptides are domestically sourced and tested in USA-based laboratories following documented quality procedures.
