You're running metabolic studies and biggest variable is peptide integrity—degraded matrial introduces noise you can't control, and inconsistent purity across batches makes replication a nightmare.
We supply semaglutide at ≥99% purity by HPLC, which basically means you're working with a tight window of active peptide form vial to vial, and the lyophilized powder holds stability at -20°C for months (usually 4-6 months or so without noticeable loss).

, CAS 910463-68-2, molecular weight 4113.6 g/mol—the GMP certifcation and COA come with every order, so you've got traceability for your protocols. It's soluble in water or sterile buffer, but don't expect it to dissolve instantly in cold solvent; let it warm to room temp first.

MOQ is 10 vials per kit, and we typically stock for quick turnaround, but check lead time if you need more than 50 kits— are scheduled monthly. Most buyers go with teh 10mg/vial format for, though the 5mg option exists if you're titrating low.
This isn't suited for in vivo work without proper formulation—the powder is research grade only, and you'll need to handle reconstitution under sterile conditions if you're going that route.
The MOQ is 10 vials, so you'd be ordering one full kit to start.
Lead time is typically 5-7 business days after payment confirmation, but we can speed it up for larger orders.
Yes, we include a COA with every order, and it confirms the ≥99% purity by HPLC.
We standardize on 10mg per vial, 10 vials per kit. Custom packaging is possible for large bulk orders—just let us know your needs.
Keep it at -20°C and protect from light. Once reconstituted, store it in the fridge and use it within a few days.
