We're running these retatrutide trial sign up batches through HPLC on every single lot—purity's consistently above 99%, and we've got the COAs to show it, though I'd suggest confirming lead time since we usually have stock but it moves fast.
Most buyers go with the 10mg or 15mg vials for weight loss research, but the 30mg is actually pretty popular for longer studies—just keep in mind the freeze-dried powder needs to stay at 2-8°C in a dry enviroment or it'll degrade faster than you'd expect.
1 box is the MOQ (10 ), and we can customize the dosage for your trial sign up program—5mg, 12mg, 20mg, 60mg, whatever you need—but the 60mg vial is tricky to reconstitute evenly, so most labs stick with the smaller sizes.
What it does is give you batch-to-batch consistency that's better than reagent grade for this applicaion, and we've handled enough orders to know the shelf life holds up for 24 months when stored properly—no surprises on the retest policy either, we'll replace if it fails within that window.
Also, the white powder looks identical across batches, but one thing I've noticed is the 12mg vials tend to clump slightly more than the 5mg—nothing that affects purity, just a handling quirk form the lyophilization process.
It's not suited for anything beyond research use, obviously, and the trial sign up customization usually adds about 20 days or so to delivery, but the certifcates are straightforward and our company can share teh HPLC traces before you commit.
We offer 5mg, 10mg, 12mg, 15mg, 20mg, 30mg, and 60mg per vial, with 10 vials per box — so you can pick the dosage that fits your study design.
Yes, the MOQ is just 1 box (10 vials), so you can start your trial without a huge upfront commitment.
Absolutely — we can customize the dosage and packaging to match your trial sign up program requirements, just let us know what you need.
We supply a Certificate of Analysis (COA) with each batch, confirming the >99% purity, so you have full quality assurance for your research.
Store it at 2-8°C in a dry environment, and it will be stable for 24 months — perfect for longer-term studies.
