At high end of our bulk pricing we're seeing costs drop to roughly £85 per gram for orders of 100 grams or more, and that's with GMP cerification and full COA included — the 99% purity holds consistently across every batch we've tested.
We've run it through HPLC ourselves, and teh chromatograms show no significant impurity peaks above 0.3% area, which is tighter tolerance than most research-grade peptide suppliers will guarantee for this molecular weight (4113.6 g/mol).

Storage is straightforward but non-negotiable: -20°C, protected from light, and you'll want to keep it dessicated — moisture ingress at that temperature can cause aggregation, and we've seen vials degrade within 2 weeks if left out.
So for sampling we do a 10mg vial at £14 or so, and the mid-tier 1-gram bag runs about £110; both ship from our UK warhouse, usually within 2 business days if our company have stock (which we typically do).

It's not suited for in vivo work without your own ethics approval, obviously, and the powder is hygroscopic enough that you should aliquot immediately upon opening — don't just reseal the bag.
Anyway, what it does is bind GLP-1 receptors with an affinity in the low nanomolar range, but we don't publish exact Ki values as those vary by assay conditions — check the COA for your specific lot.
Our MOQ is typically 10 grams for wholesale orders, but we can discuss smaller quantities depending on your setup. Just reach out and we'll see what works for you.
Standard lead time is 5-7 business days after payment confirmation, with faster shipping options available if needed. We'll confirm the exact timeline when you order.
Yes, absolutely — a full COA is included with every order, covering purity over 99% and other specs like molecular weight. GMP documentation is also available on request.
We offer custom packaging options, so you can choose vial sizes or add your own labels for a small fee. Just let us know what you need when you place the order.
Store it at -20°C, protected from light — that's key for maintaining that 99%+ purity over time. Avoid freeze-thaw cycles, and it'll stay good for months.
