We've seen enough supliers fudge peptide purity to know that consistent 99.9% by HPLC actually matters—this one holds that spec across batches, and COA form each lot is sent with the shipment (usually 2-4 weeks lead time for larger orders).

It's a white powder, soluble in water, and the molecular weight works out to 246.71 g/mol, but what you really care about is that CAS 86-39-5 stays locked for reordering; don't expect it to dissolve instantly, though—give it a gentle swirl for a minute or so.

Storage is a pain point nobody warns you about: you'll need to keep it at 2-8°C, protected from light, or teh peptide degrades faster than most buyers expect, so plan your cold chain before the shipment lands.
The 5mg and 10mg vials are the most commonly ordered, but the 15mg option is actually easier to handle for serial dilutions if you're running multiple assays—just check our stock, because we sometimes run short on the 15mg format.

Payment terms are standerd net 30 for approved accounts, but we also take wire transfers or PayPal for first-time orders; MT103 copies are provided within 24 hours of payment clearing, and the TDS and SDS are emailed before the goods ship.
