Getting consistent dose-response data in metabolic research is a headache when your peptide degrades between experiments — this lyophilized powder eliminates that variable from the equation, basically. We see a lot of labs switching to it because the 99% purity by HPLC means fewer byproducts muddying your results, and that CAS number 2023788-19-2 is what you’ll quote for customs clearance.
Molecular weight sits at 4813 g/mol with teh formula C225H348N48O68, so it’s a sizable peptide that needs careful reconstitution — most buyers go with the 10mg vial for smaller pilot studies. You’ll get it as a lyophilized powder in sealed vials, and the shelf life is over two years if you keep it at -20°C for long-term (0-4°C works for a couple weeks). Don’t expect it to dissolve in plain water without some buffer optimization.
It’s pretty much useless for anything outside receptor-targeted metabolic work — don’t try to use it in cell viability assays or anything with high serum content. dual GIP/GLP-1 agonism makes it a better fit for glucose regulation studies than single-target analogs, and some of our buyers pair it with exendin-4 for comparative binding affinity runs. One concrete thing we’ve noticed: the 15mg vials are easier to handle if you’re doing multiple dilutions in one session.
We usually have stock of 5mg, 10mg, 15mg, and 30mg vials, but the 30mg option has a lead time of 20 days or so (check before ordering). Each batch ships with a COA form our third-party lab, though the grade is cosmetics grade — that means it’s not sterile and shouldn’t be used in any in vivo work. Storage in a dark, dry place is critical; moisture hits this peptide hard, and re-hydrated solution doesn’t hold stability past 48 hours even at 4°C.
Also, the packaing is 10, so if you need 50 vials or something, you’ll be ordering 5 boxes. We don’t break boxes for single vials — MOQ is one box per strength. You can mix strengths in the same order (say 3 boxes of 10mg and 2 boxes of 15mg), but confirm total quantty with your rep for custom requests.
Yes, we offer custom options. You can choose 10mg or 15mg per vial, as well as 5mg and 30mg. Just let us know what you need when you order.
We typically require a minimum of 10 vials per order, but that can be flexible depending on the quantity and packaging you choose. Check with us for specifics.
Yes, we can supply a COA showing the 99% purity and other specs. Just request it when you place your order, and we'll include it.
Store it in a dry, dark place. For short-term use, keep it at 0–4°C, and for long-term storage, -20°C works best. Avoid moisture and light.
Yes, it's cosmetics grade and intended for research use only. Lead time for custom orders like 10mg or 15mg vials is usually 7–10 business days after confirmation.
