Went with the 5mg vials this time, 30 units — we usually have stock, but confirm lead time if you need more than that. CAS is 2381089-83-2, purity runs north of 99% by HPLC, and molecular weight sits around 4.1 kDa. It's a lyophilized white powder, soluble in water at 5mg/ml — pretty straightforward to reconstitute if you've handled peptides before.
What it does is hit three receptors at once — GCGR, GIPR, and GLP-1R — which is why labs are using it for metabolic work rather than the single-target stuff. Most buyers go with the 10mg for mouse dosing, but 5mg is fine for initial screening. It's not suited for anything beyond research use, obviously — no in vivo work without proper protocols.
Storage is -20°C, and they claim a 3-year shelf life if you keep it there, but I'd rotate stock within 12 months or so. One thing you'll notice is teh powder can be slightly electrostatic when you open the vial — tap it gently before reconstituting, or you'll lose materail.
The EC50 values are pretty tight — 0.0643 nM for human GIPR, 0.775 nM for GLP-1R, and 5.79 nM for GCGR — so it's more potent on the GIP side than most triple agonists I've seen. Actually, that's better than reagent grade for this type of work, and the COA backs it up.
Also, the 30mg vials are easier to handle if you're doing larger batch studies — fewer vials to open, less risk of contamination. We've used the 15mg size before, and it's fine, but the 5L drum analogy doesn't apply here; stick with sizes that match your typical weekly usage.
Yes, every batch is tested with HPLC to guarantee >99% purity. We provide a Certificate of Analysis with each order so you can verify it yourself.
We don't have a strict MOQ — you can order a single 5mg vial to test. For larger quantities, just ask, we can work out volume pricing.
Absolutely, a COA with purity, identity, and other specs is included for every batch. Just request it when you order.
Keep it at -20°C in a freezer, and it'll stay stable for 3 years. Avoid repeated freeze-thaw cycles after reconstitution.
No, it's strictly for laboratory research only — not for human or veterinary use. It's meant for studies on metabolic disorders, diabetes, or obesity.
