It's not going to be a quick fix for anyone expecting immediate results in vivo—this is a research-grade peptide, not a finished drug, so you're looking at weeks of protocol work before you see meaningful data.
We've been running these vials through HPLC and mass spec, and teh purity consistently hits 99.9% or better; the COA shows no major truncations or side products, which is tighter than what we saw form some other supliers last quarter.

The lyophilized powder is pretty straightforward to handle, reconstitutes in water or buffer with no visible residue, and we store it at 2-8°C after that—just be aware the shelf life on dry powder is about 18 months, give or take, so check the lot date before ordering bulk.

Most buyers go with the 10mg vial for standerd metabolic assays, but the 15mg option works better if you're running at higher concentrations; the MOQ is one box of 10 vials, and we usually have stock, but confirm lead time (typically 2-4 weeks) if you need it fast.
Also, this peptide is not suited for oral administration studies—it degrades quickly in GI conditions, so you'll want to stick with subcutaneous or IV routes for any meaningful receptor activation data.
