How every lot is calibrated
Synthesis & lyophilization
Peptides are synthesized and supplied as a stable, lyophilized powder for laboratory handling.
HPLC purity
High-performance liquid chromatography quantifies purity for each production lot.
Mass-spec identity
Mass spectrometry confirms molecular identity against the expected mass.
COA issued & lot-matched
A certificate of analysis is issued and tied to the lot, so every order is traceable.
What does "research use only" mean?
Every product is a laboratory reference standard supplied solely for in-vitro research - not for human or veterinary use, and not a drug, food, supplement, cosmetic, or medical device.
Is a Certificate of Analysis included?
Yes - every tested lot is matched to a third-party COA covering identity and purity. Browse and download them in the COA Library, before or after purchase.
How do I pay?
Choose a method at checkout, send the total directly, then email a screenshot as proof. Your order is reserved and ships once payment is confirmed - no card is charged on the site.
Who can purchase?
You must confirm you are at least 21 and a qualified researcher (or authorized to buy for a research institution). This is recorded with every order.
