The pricing really breaks down in your favor the more you move up — for a single 5mg vial you’re looking at around £45, but once you hit the mid-tier of 50 vials or so that drops to roughly £32 each, and at bulk orders of 200+ vials we’re talking about £22 per vial, which is pretty much half the sample cost.
What gets most researchers’ attention first is that purity spec — >99.0% — and it’s not just a number on paper, because we’ve had batches consistently hit 99.3% by HPLC, and that tighter tolerance means fewer variables when you’re running or long-term metabolic studies.
We usually have the 10mg and 15mg vials in stock, but for the 40mg or 60mg sizes you’ll want to confirm lead time (usually 2-4 weeks) since those custom sizes aren’t something every distributor keeps on hand, and the 5L drum is easier to handle if you’re reconstituting in bulk anyway.
Actually, one thing buyers don’t always think to ask — teh lyophilized powder can clump slightly if storage fluctuates above 25°C before reconstitution, so keep it in a cool, dry place, and we’ve found the 20mg vials are the sweet spot for most labs since they minimize waste without needing to pool multiple vials.
We don't have a strict MOQ on custom sizes. You can order as little as a single vial at 40mg or 60mg, but bulk discounts kick in at 10+ vials.
Yes, every batch comes with a COA showing the actual purity, typically verified by HPLC. Just request it when you place your order.
For stock sizes like 5mg or 10mg, we ship within 24 hours. Custom sizes may take 3–5 business days to prepare. Delivery to the UK usually adds 5–7 working days.
Keep it in a cool, dry place away from direct sunlight—room temperature around 20–25°C works fine. Do not refrigerate before reconstitution, as moisture can affect stability.
Absolutely, we can fill custom amounts like 25mg per vial. Just let us know the exact dosage you need, and we'll adjust the order and pricing accordingly.
