Bulk Retatrutide Supply - Professional Peptide Synthesis Provider

We're running it at >99% purity by HPLC, which is pretty much the baseline for reliable dose-response work in metabolic studies, and the reconstitutes cleanly in standard aqueous buffers or saline—though we usually recommend aliquoting after reconstitution to avoid freeze-thaw degradation.

Storage is -20°C in a dry enviornment, and under those conditions we've seen the shelf life hold at 2 years or so, but if you're opening vials frequently you'll want to be quick about it; moisture ingress is teh main killer here, and we've had labs lose potency in 6 months if they're sloppy with desiccants.

5mg or 10mg per vial depending on your batch size, and the 10mg format is actually easier to handle for most in vivo work because you get fewer vials to reconstitute—we usually stock both, but MOQ is one box anyway, so you can mix if you call ahead.

We do custom synthesis for non-standard sequences or modifications, but lead time on that is typically 4-6 weeks (check availability first), and we'll run an extra HPLC and MS for confirmation if you request it on the PO.

This isn't good fit for cell culture work at high concentrations unless you're filtering it yourself—the lyophilization process leaves trace residual solvents that are fine for animal models but can throw off sensitive assays, and we don't routinely test for endotoxin unless you specifically ask.

Also, the COA comes with every order, but we don't include the raw HPLC trace in standdard package—you can request it, and we'll email a PDF within 24 hours of shipment.
