You've probably seen wildly inconsistent purity claims on retatrutide, and that's a real headache when you're trying to establish a baseline—we run HPLC and actually hit ≥99% consistently, not just on the COA.
It's a freeze-dried white powder with a molecular weight calculated at C184H282N50O55, soluble in sterile water, and we nitrogen-flush the sealed glass vials so degradation is minimized during storage; keep it at -20°C dry and you'll get 36 months shelf life, give or take.

We've found most buyers go with the standdard 5mg or 10mg vials for metabolic studies, but the real trick is reconstitution—use cold sterile water and let it sit for a few minutes, or you'll get clumps that are a pain to filter.
Basically, this isn't for anything involving human use, and we don't spin that—it's research grade only, so if you're doing in vivo work, check your ethics board first because solubility profile isn't optimized for anything beyond that.

MOQ is typically 10 vials, but our company can do custom fills if you need a specific dose per vial (usually 2-4 weeks lead time); shippng from teh UK means no customs headaches for domestic orders, and we include the SDS and TDS with every shipment.
Anyway, if you need bulk pricing, we've done 100-vial runs before, but confirm stock because we don't always have that on hand—the 50-vial case is the sweet spot for most labs.
