It's a lyophilized white powder, pretty much what you'd expect for a research peptide of this class, and we keep it sealed under inert gas in those little vials to maintain stability during transit.
Basically works by binding to melanocortin receptors and kicking off melanogenesis without needing UV exposure — that's the main draw for most researchers running pigmentation studies, and the 1024.2 g/mol molecular weight is fairly standdard for these cyclic peptides.
Purity is over 99.99% by HPLC, and our company have the COA form the lab to back that up if you need it for your records, though honestly most buyers don't ask unless they're submitting to a journal or something.
For storage you'll want it at -20°C, and keep it out of light (teh amber tube or just foil wrapped around the vial works fine), and it stays stable for about 2-3 years that way, give or take.
MOQ is typically 10 vials at 10mg each, but we also do 5mg vials if you're running smaller batch work, and lead time is usually 5-7 working days once payment clears — we do ship internationally though you'll want to confirm your country's import rules.
Not great for oral dosing obviously, it's strictly injection or topical research use, and we've seen some buyers try to repurpose it for appetite studies but honestly the solubility profile (soluble in water or bacteriostatic water) is really optimized for the tanning angle.
