Inquiry
We got your inquiry about the retatrutide, and actually, we've been supplying it for a while now — most buyers go with the 10mg vial for standdard workups, though the 5mg is better if you're just testing solubility or running small pilot batches.
Purity is verified at 99% or better by HPLC, which is tighter than some of the bulk stuff we've seen out there, and we'll include the COA with each shipment; the endotoxin level is under 1 EU/mg, so it's pretty clean for research use.
It's freeze-dried in sterile glass vials (sterile filtered before lyophilization), and you can reconstitute it in water or buffer without issues — just keep it at -20°C for long-term storage or 4°C for a few weeks, and the shelf life is 36 months or so if you handle it right.
Not really suited for oral dosing at all, since it's a peptide, and we usually have stock on the 2mg and 10mg vials, but the 50mg size sometimes has a 2-week lead time (check on that before you finalize).
One thing that comes up a lot is documentation — we include the full COA and mass spec data, but if you need the SDS or a more detailed TDS for your lab's records, just let us know in the order notes.
Anyway, our company can ship roughly 20-30 vials within a week if you order the 5mg or 10mg sizes, and the pricing is better than reagent-grade alternatives for this spec — just confirm the quantty and we'll send over teh invoice.
We can do as few as 10 vials per specification, but if you need less, just ask—we sometimes accommodate smaller research orders.
Lead time is typically 3-5 business days after payment confirmation, and we ship on ice packs to keep the powder stable during transit.
Yes, every batch comes with a CoA showing HPLC purity ≥99% and endotoxin levels <1EU/mg—just request it with your order.
We standardize on those four sizes, but if you need a custom fill, let us know the amount and we can quote it for bulk orders.
Keep it at -20°C for long-term storage, or 4°C if you're using it within a few weeks—just avoid repeated freeze-thaw cycles.
