It's not for human use, full stop — that's the first thing you need to know, and we don't sugarcoat it, but for legitimate lab work, purity holds up at ≥99% by HPLC, and we've seen consistent results across batches with our in-house testing protocols.
Each vial comes lyophilized, white powder, and we run a COA with every order that includes the HPLC trace and mass spec confirmation — you're not guessing at what you've got, and we typically stock 5mg, 10mg, or 15mg vials (10 ).
Storage is straightforward: -20°C for long term, though 2-8°C works for a few weeks or so, and the shelf life is over 2 years if you keep it cold — basically, don't let it sit out on the bench.
We've had buyers ask about retesting after a year, and our policy is straightforward: if it's within the shelf life and stored properly, we'll reissue a COA for a small fee, but most labs just order fresh stock for critical assays.
Teh molecular weight is 4113.6 g/mol, and it's soluble in water or buffer — one thing you might not think to ask is that the 15mg vial is a bit more prone to static cling when reconstituting, so tap it gently before adding solvent.
