We've had suppilers before that talked a big game but couldn't deliver consistent white powder, so it was a relief when this suppiler's 99%+ purity held up across the first three batches we ordered for our MT2 and Retatrutide work. The 5mg vials are a solid baseline, but most buyers go with the 10mg or 15mg for most assays—the 30mg is better if you're running high-dose trials, though it's not ideal for micro-dosing work.

You'll get sealed vials, which is basically teh only way to keep the powder from clumping, and each one comes with a COA and HPLC data—usually our company have stock on the common sizes, but confirm lead time if you need a specific concentration or a rare peptide like Epitalon. The storage is 2-8°C, and it's pretty important to keep it dry and away form light, or you'll lose potency within 20 days or so.

What it does is give you a reliably tight tolerance—roughly ±2% on the claimed mass—which is better than reagent grade for this, and we've found the 10mg format is easier to handle when reconstituting for in vivo work. One thing you might not think to ask: the vials are pre-scored at the neck, so opening them doesn't generate glass fragments like some cheaper ones.

Anyway, MOQ is just one box, and they usually ship within a week from their China warhouse—we've tested three different lot numbers now, and the HPLC profile is basically identical each time. Something we've noticed is the 5mg vial is actually a bit trickier to weigh accurately if you're pipetting by hand, so the 10mg might save you a headache.
Yes, every batch comes with a CoA showing ≥99% purity. Just let us know if you need it with your order or sample request.
Lead time is usually 3-7 business days after payment, depending on the quantity and size mix. We ship from our China facility via express courier.
Absolutely, you can combine sizes like 5mg, 10mg, 15mg, or 30mg in the same order. MOQ is just 1 box total, so feel free to mix.
Keep sealed vials in a fridge at 2-8°C, dry, and away from light. Stored properly, they last a full 24 months from production.
Yes, samples are available. Just cover the shipping cost, and we'll send a small quantity for you to test purity and handling before placing a bulk order.
