We’ve got stock ready to ship from our US warehouse now, the 10mg/vial format usually moves faster but both are avaliable in full boxes of 10 vials.
The lyophilized powder hits ≥99% by HPLC, white and consistent, and we’ve held it at 2-8°C through the whole cold chain so you’re not dealing with degradation on arrival—shiping is typically 2-3 business days with gel packs.
CAS is assigned as a research compound so customs clearance is straightforward, but confirm your institutional protocols because we don’t ship to residential addresses for this one.
Molecular weight sits around 4.1kDa, which is pretty much what you’d expect for a synthetic peptide of this class—better solubility than some older analogs when you reconstitute with sterile water or PBS.
Actually, the shelf life is 24 months from production if kept in the dark at 2-8°C, but we’ve seen it hold beyond that in lyophilized form (usually fine for another 6 months or so).
MOQ is one box, 10 at either 5mg or 10mg per vial, and we include COA with each shipment—no need to request it seprately.
Yes, we provide a COA with every batch — you'll get the actual HPLC test results showing ≥99% purity. Just request it with your order.
We do sell single vials, but our standard packaging is 10 vials per box. If you need just one for testing, that's fine, but the box pricing gives you a better per-vial rate.
Domestic orders typically arrive in 3-5 business days via USPS or FedEx, and we provide tracking as soon as it ships. International orders vary but are also tracked.
We currently only offer Retatrutide in 5mg and 10mg vials. Custom sizes would require a larger volume order and longer lead time — contact us to discuss it.
Store the lyophilized powder at 2-8°C in the dark — it's good for 24 months. Once reconstituted, keep it refrigerated and use within 7-10 days for best results.
