Pricing breaks down pretty clearly — 5mg vials at £45 for samples, mid-tier orders of 50 vials drop to £32 each, and if you're moving 200+ units we're looking at roughly £22 per vial, and that's where most buyers actually land because the savings add up fast.
It's 99% purity by HPLC, white powder as you'd expect, CAS 910463-68-2, and we store everything at 2-8°C from production right through to dispatch — the MW is 4113.6 g/mol, which matters for accurate reconstitution, but basically what you're getting is pharmaceutical research grade that's been tested across multiple batches.

Most people don't realize that the 10mg vial is actually the sweet spot for cost per mg — we've had a few labs try the 15mg and find it's harder to aliquot without waste, so most buyers go with the 10mg unless they've got a specific protocol that calls for a different dose.

The lyophilized powder reconstitutes fine in sterile water or PBS, but it's not suited for anything beyond in vitro work — we can't and won't advise on in vivo because that's outside our scope, and honestly purity tolerances are tighter than what you'd get from some generic peptide suppliers anyway.

Custom packging is doable if you're ordering 500 vials or more — our company can do 20mg vials or different labeling, but the standerd 5mg/10mg/15mg is what we keep in stock, and lead time for custom runs is usually 20 days or so (check lead time when you order).
Logistics for UK delivery — we ship from a warehose in Manchester, so it's typically 3-5 working days via courier, and we include a COA with every order but you'll need to request teh SDS separately.
