Having that dual GIP and GLP-1 mechanism means you're not stuck with just one pathway for metabolic research — it basically lets you look at how both receptors interact, which is pretty much reason most buyers go with the 10mg or 30mg vials for longer studies.
At ≥99% purity by HPLC, you're getting a white powder that's consistent across batches, and teh CAS is 6893-02-3; we usually have stock, but confirm lead time if you need more than 50 vials or so.

Storage is straightforward — keep it at 2-8°C and protect from light, and what it does is bind effectively to both GIP and GLP-1 receptors with a partciular affinity for GIP (usually 2-4 weeks is fine for reconstituted matrial, but check the TDS for specifics).

A detail you might not think to ask: the 5mg vial is easier to handle for short-term dose-response work, while the 30mg is better if you're running multiple assays — but it's not suited for anything outside research use, and we don't have data on human consumption.
Also, the molecular weight is roughly 4813.5 g/mol give or take, and we issue a COA with every order.
We can do as little as 10 vials for the 30mg size. For smaller vials like 5mg or 10mg, the MOQ is a bit higher at 20 vials. Let me know if you need a custom quantity.
Usually 7-10 business days after payment is confirmed. If you're in a rush, we can expedite to 3-5 days for a small fee.
Yes, we include a COA with every batch. It shows the HPLC results verifying the purity, plus the molecular weight and appearance data.
We can do that. Just specify it in your order notes. The amber vials add a bit to the cost, but they offer better light protection during storage.
Once opened, we recommend using the powder within 30 days if stored properly at 2-8°C and protected from light. After that, the purity may start to drop.
