It's not a weight loss drug approved for humans, so you can't use it that way, but for metabolic research it's actually one of the more interesting triple agonists we've seen in a while — the glucagon, GLP-1, and GIP receptor activity means you're hitting multiple pathways at once, which is pretty much what the field is chasing right now.
We usually have the 5mg and 10mg vials in stock, roughly 200 units or so at any given time, but confirm lead time if you need more than that because MOQ can vary depending on teh batch. lyophilized powder is white and dissolves fine in water or bacteriostatic water — no weird clumping, which is nice for reconstitution.
Purity runs at 98% or better by HPLC, and we do check every batch for consistency, but honestly it's tight enough that most researchers don't bother asking for COA unless they're running something really sensitive. Storage is straightforward: keep unopened at -20°C, and once you reconstitute it, 2-8°C is fine for a week or so.
What it's not great for is long-term stability at room temp — leave it out for a day and you'll see degradation, so don't plan on leaving it on the bench. The shelf life is 24 months when stored properly, but we've had some batches hold up longer if they're kept cold the whole time.
For weight management studies, the 10mg vial is usually what people go with because you get more materail per vial, but the 5mg works fine if you're doing smaller assays or just testing solubility first. One thing you might not think to ask: the peptide sequence is stable enough that you don't need to use RNase-free water, though we still recommend it.
