We’ve been moving a fair amount of this into UK labs recently and most buyers are running metabolic or glycemic studies on it, roughly 10mg to 20mg per vial depending on their protocol and typical weekly dosing, but our company can’t always say what exact results they’re getting since that varies.

It’s a lyophilized powder (white, pretty standard) stored cold at 2-8°C, dry and dark, and we ship it in 10mg vials with 10 — basically what you order is what you get, though sometimes a box might have an extra vial if we’re topping up form a batch.

The purity is checked via HPLC and it’s always ≥99%, so you’re getting consistent stuff batch to batch, but we don’t test for endotoxins or sterility ourselves unless you specifically ask for that (we usually have it, but confirm lead time).
For UK orders we include a basic import document with the shipment, usually a packing list and a certificate of analysis, but customs might ask for a research-use-only declaration depending on your region, which we can provide within 2-3 days or so.

This isn’t suited for human or veterinary use at all, obviously, and some buyers have told us the 10mg vials are easier to reconstitute than the bigger sizes because teh powder dissolves quicker in bacteriostatic water — just a practical detail.

Also, we recommend storing it in a fridge with stable tempearture because fluctuations can affect the powder’s solubility over 30 days or so.
We require a minimum of 1 box, which contains 10 vials (10mg each). So you'd be ordering at least 100mg total.
Yes, we include a certificate of analysis with every order that shows the ≥99% purity confirmed by HPLC. Just request it when you place your order.
We don't break down the 10-vial boxes, sorry. You'd have to order the full box if you want a trial, but we do have flexible order quantities beyond the MOQ.
Orders are usually dispatched within 1-3 business days, and delivery to the UK takes about 5-7 working days via courier. We'll send tracking once it's shipped.
Keep it in the fridge at 2-8°C, dry and away from light. Don't freeze it, and make sure the vial stays sealed until you're ready to use it.
