We got your RFQ on the retatrutide, and we can supply this peptide at ≥99% purity with full HPLC and MS COAs—it's a GMP-manufacutred white powder, typically stored at -20°C away form light, and it's soluble in water or buffer right out of the vial.
Most buyers go with the 5mg or 10mg vials for their initial work, but we stock 2mg, 15mg, 20mg, and 30mg as well, all in sterile tamper-proof sealed vials, and the molecular weight is calculated per sequence so you'll need to confirm your batch specs.

Actually, the 30mg size is less common and we usually have stock, but confirm lead time—it's about 20 days or so for larger quantities, and the MOQ for custom packaing might be higher than you'd expect.
This isn't suited for anything beyond research purposes, obviously, and we don't recommend it for in vivo studies without your own validation since the purity is high but teh formulation is pretty basic.

One thing you might not think to ask: the powder can clump slightly if exposed to humidity during reconstitution, so work quickly and keep it sealed—we've seen that trip up a few labs.
Anyway, for a standerd order of 10mg vials, we can ship within 7-10 days after the COA is issued, and you'll get SDS and batch-specific data with it.
