Just keep in mind this is strictly for lab work—it's not formulated for human use, which is actually why most researchers source it form us, since we keep the documentation clean and the COA matches batch to batch.
It's the 10mg per vial format that most buyers go with, and we had one client who was pretty impressed with how the white powder handled reconstitution even after sitting in the fridge for three weeks or so.

The purity holds at ≥99.9% confirmed by HPLC, and that's better than reagent grade for this kind of metabolic study; the storage at 2-8°C isn't hard to manage as long as you keep the light off it.

We usually have stock, but confirm lead time right now—it's roughly 20 days for orders around 50 units or so, and our company can adjust box count if you're comfortable with partial boxes.

Anyway, the CAS is 2023788-19-2 and we ship with teh SDS and TDS included by default, so you'll have everything for your protocol review.
It basically works well for dual receptor assays, but don't expect it to fit solubility studies without that PEG-modified lysine chain already being accounted for in your buffer calculations.
We require a minimum of one box — that's 10 vials, each 10mg — but we can work with you on larger volumes if needed.
Orders are usually dispatched within 3-5 business days after payment clears. Delivery time depends on your location and shipping method.
Yes, we include a full CoA with every batch, confirming the ≥99.9% purity and other specs like appearance and molecular identity.
Currently we only offer the 10mg/vial format in boxes of 10. Custom packaging or smaller vial sizes aren't available for this product.
Store it at 2-8°C in a refrigerator, and keep it away from light. If stored properly, the powder stays stable for up to 24 months.
