Why Researchers Choose NoProp Peptides
Every Batch Tested Independently
HPLC purity analysis and ESI-MS molecular weight verification from an independent lab. Not in-house testing. Not “upon request.” Every production run, every time. The COA ships with your order.
99%+ or It Doesn’t Ship
Our minimum purity threshold is 99% as verified by HPLC. Batches at 98.5% get rejected. The difference matters — impure peptides introduce variables that compromise your data and waste your time.
Proper Synthesis & Cold-Chain
Solid-phase peptide synthesis, proper lyophilization, and cold-chain storage from production to shipment. Peptides degrade at room temperature — how they’re stored matters as much as how they’re made.
