It's not intended for anything beyond lab work, and we're pretty clear about that — this retatrutide is strictly for research use only, so if you're thinking about anything else, this isn't right fit, but for controlled studies it holds up well because we run HPLC and keep the purity tight.

What we've found over the years is that batch-to-batch consistency matters more than most buyers realize, and we test each lot with a COA that includes teh actual ppm results (usually within a narrow range) so you're not guessing when you set up your protocol.

Storage is straightforward but critical — keep it in a cool, dry place in the orginal glass vials with the rubber stopper sealed, and you'll get the full 2-year shelf life, though we've had customers report it's still good past that point if the desiccant pack hasn't been compromised.
The 10mg dosage is actually the most common pick for standerd assays, but our company can customize to 5mg, 15mg, or 20mg depending on your batch size, and the MOQ is typically 10 (5ml volume each) — we usually have stock, but confirm lead time if you need more than 50 units or so.

One thing that catches people is the retest policy: if you open a vial and it doesn't match the COA within 30 days, we'll replace it, but you have to store it properly first — we've seen issues when vials are left out in humid conditions, and that's on the end user.

Anyway, the white powder form is easier to reconstitute than some analogs we've handled, and the rubber stopper closure holds up well to repeated punctures if you're using a sterile technique, but it's not designed for high-throughput automated systems.
Yes, the dosage is customizable. Just let us know the exact amount you need per vial, and we can adjust it for you.
Typically, a standard order of one box—10 vials—ships out within 3 to 5 working days. Custom dosages might add a day or two.
Absolutely. Every batch we ship comes with a CoA showing purity and quality specs. Just request it with your order.
Yes, it is. Stored in a cool, dry place, the powder stays stable for the full 2-year shelf life. The rubber stopper keeps it sealed tight.
For custom dosages, the MOQ is usually one box of 10 vials. No huge minimums, so it works for small lab runs.
