We're holding stock right now on teh 10mg vials, so lead time is usually just a few days unless you need custom peptide synthesis — that'll run 2-3 weeks depending on sequence and scale.
Purity is at 99.9% or better by HPLC, and our company can ship the COA with the order if you need it for your records; it's pharmaceutical grade, CAS 910463-68-2, molecular weight 4113.58 g/mol.

Storage is critical here — it have to stay at -20°C in a dry enviornment, and we ship with gel packs in insulated boxes during warmer months so it doesn't degrade in transit (usually 24-48 hours domestic, 3-5 days internaional).

Basically, each vial holds 10mg of semaglutide, and most buyers go with the 10mg vial for smaller research batches rather than ordering bulk powder.

This isn't designed for any in vivo use beyond research — it's strictly for lab work, so don't expect it to perform like a clinical formulation in cell-based assays.
Also, we can do custom peptide synthesis with tighter tolerance than reagent grade if you need specific modifications, but the MOQ jumps to about 50 vials or so for custom orders.
