We've been running this peptide for years, and most buyers go with the 5mg vial for retatrutide trial sign up studies — it's easier to handle during reconstitution than the 2mg option, though both work fine depending on your dosing needs.
HPLC and MS data come with every batch, and the COA confirms ≥99% purity, which is better than reagent grade for this kind of work; the molecular weight sits at 975.06 g/mol, and you'll want to store it at 2-8°C after reconstitution (usually stable for about 20 days or so).

Lead time is 1-3 working days, and MOQ is just one box of 10 vials — we usually have stock, but confirm lead time if you're ordering more than 50 units or so, as bulk can shift availability.
It's not suited for anything beyond research use, basically, and can be a bit tricky if you're not careful with reconstitution — we've seen labs accidentally leave it out too long and lose potency.
Also, the 2mg vial is pretty much standerd for smaller trials, but teh 5mg gives you more flexibility per dose — just check your protocol because some studies need tighter tolerance than what our company offer on the 2mg format.
Just 1 box — that’s 10 vials. So you can start with as few as 10 vials if you’re testing for Retatrutide trials.
We process and ship within 1-3 working days. Pretty fast turnaround for research peptides.
Every order comes with a Certificate of Analysis (COA), plus HPLC and MS reports. You’ll have the purity and identity data right there.
Yes, the per-vial amount is customizable. Just let us know what dosage you need for your trial, and we can adjust.
Keep it refrigerated at 2-8°C after reconstitution. The powder itself is stable at room temp before mixing.
