Basically, it's retatrutide as a white freeze-dried powder at 99% purity or better by HPLC — we run every batch through that. 2. Most buyers go with the 10mg vial for their studies, and we've got 2mg, 5mg, and 15mg too, but the 5mg is easier to handle if you're titrating. 3. You'll want to store it at -20°C away form light, and it's good for 36 months or so if you do that right. 4. We ship with a COA and MS, sometimes the HPLC trace, depending on order size. 5. MOQ is just one vial, so you can test it without committing to a ton — we do about 100,000 vials a month, so stock is usually fine, but confirm lead time for non-standdard amounts. 6. Not for human use, obviously, and it's better than reagent grade for this applicaion, but we don't do private labeling unless you're a qualified institution.
