So you're looking at Retatrutide acetate, CAS 2381089-83-2, and that 99% purity is what we've been running with for last six months or so — it's pretty much the standdard we expect for in vivo work.
The triple agonist profile is what makes this one interesting, and the EC50s we've seen on our COAs match the literature: roughly 0.0643 nM for the human GIPR and 0.775 nM for GLP-1R, but you'll want to confirm that against your own batch since we've had slight variation between lots.
We store it refrigerated, lyophilized powder form, and the shelf life is 2 years if you keep it dry and away from light — that's standard for peptide acetates, though we usually reconstitute within 30 days of opening the vial.
One thing that caught us off guard: this compound isn't great for acute oral dosing studies because of the peptide degradation in GI, so we stick to subcutaneous or IP routes for our obesity research, and teh weight reduction data has been consistent.
Our last order was 10, 10mg per vial, shipped form a UK source with HPLC and MS COAs included — lead time was about 20 days, but we confirmed stock before placing the order.
We don't have a strict MOQ on this one — you can order as little as a single box of 10 vials. If you need larger quantities, just let us know and we can work that out.
Once payment clears, we ship within 1-2 business days. Delivery to the UK usually takes about 5-7 days via courier.
Yes, each batch comes with a COA showing 99% purity confirmed by HPLC. Just request it when you place your order and we'll include it.
Keep the powder refrigerated at 2-8°C, dry, and away from direct light. Once reconstituted, it's best used within a few days — check our handling guide for exact storage times.
Right now we offer fixed sizes of 10mg, 15mg, and 20mg per vial, packed 10 vials per box. If you need a different size or bulk packaging, contact us — we can sometimes arrange custom orders for larger volumes.
