PROTOCOL · FAQ
Common research questions.
How do you verify peptide purity?
Every batch is tested by an independent third-party laboratory using High-Performance Liquid Chromatography (HPLC) for purity quantification and mass spectrometry for structural identity. Lots that don't clear our 99% purity floor are not released. The full Certificate of Analysis is published on each product page.
Where is the Certificate of Analysis (COA) for the lot I'd receive?
Each product page links to the COA for the current shipping batch. After purchase, the COA for your specific lot is permanently attached to your order record. Past COAs are also accessible via your account.
How should I store the compounds when they arrive?
Lyophilized (freeze-dried) vials should be stored in a freezer at -20°C, away from light. Once reconstituted with bacteriostatic water, store in the refrigerator at 2–8°C and use within 30 days. Avoid repeated freeze-thaw cycles, which degrade peptide integrity.
How fast do orders ship?
Orders placed before 2pm EST ship the same day from our US-based facility. Temperature-sensitive compounds ship in cold-chain insulated packaging with gel packs. Tracking is provided via email.
Are these products approved for human or veterinary use?
No. All products sold by Merit Peptides are intended strictly for laboratory and scientific research use only. They have not been evaluated by the U.S. Food and Drug Administration and are not for human consumption, veterinary use, or any therapeutic application.

Tiered discounts apply automatically at checkout: 10% off when you order 3 or more of any compound, 15% off on orders of 6 or more, and 20% off on orders of 12 or more. No coupon code required.
Are your products manufactured in the US?
