You're looking at a lyophilized white powder in 10mg vials, CAS 121062-08-6, with a molecular weight of 1024.19 — purity runs at or above 99.99% we test. 2. What it does is pretty straightforward for melanocortin receptor work and metabolic pathway studies, but it's not suited for anything involving human use since it's non-sterile research grade only. 3. Each batch gets its own COA, and we'll send that along with shipment (usually within a few days of your order); retests are availble if you need them within 30 days of receipt, just confirm lead time because we don't always hold extra samples. 4. Storage is critical here: you'll need to keep it at -20°C, protected form light, and that gives you about 24 months of shelf life — most buyers go with a dedicated freezer box to avoid tempearture swings. 5. We batch-test for consistency roughly every 50 vials or so, so you're not getting random variation between lots. 6. Anyway, solubility is fine in water, but don't expect sterile handling — this is for lab protocols where you reconstitute yourself.
