Getting weight loss study supplies that don't degrade mid-experiment was a constant headache—six months in, lead investigator basically stopped trusting anything we'd sourced locally.
What this batch does is hold HPLC purity above 99% on every vial we sampled, the reconstitutes clean in water so nobody wastes half the run trying to filter out clumps.

663.43 g/mol molecular weight, CAS 53-84-9, and the endotoxin came back below 1.0 EU/mg; we usually store at -20°C away form light, though the shelf life claim of 3 years seems ambitious if you open a vial and don't use it quickly.
Each box holds 10 sterile vials with rubber stoppers, and you can pick 500mg, 750mg, or 1000mg per vial depending on your dosing needs—most buyers go with the 750mg for easier math.
It's definately not suited for anything topical or oral in my opinion, and bulk customiaztion is avaliable if you ask ahead (usually 2-4 weeks lead time for custom fills).
