It's a lyophilized powder, CAS 910463-68-2, and we're seeing steady demand from UK labs for research-grade semaglutide — purity runs ≥99% by HPLC, which matters for consistent peptide reconstitution.
Actually, we've had a few buyers ask about batch-to-batch variability, and what we typically do is hold a reserve sample form each production run for 6 months or so.

Storage is straightforward: keep it dry and dark at 0-4°C short-term, or -20°C if you're holding it longer than a few weeks, and it's stable over 2 years that way.

4, our company supply in custom vial sizes, usually 5mg or 10mg depending on your protocol, and MOQ is flexible for bulk orders.

One thing you probably don't need it for is formulation work — it's research grade, not pharmaceutical, so solubility profiles can vary a bit between batches.
For UK dilevery, we typically ship within 48 hours of order confirmation, though customs clearance can add 3-5 days, so plan accordingly.
We don’t have a strict MOQ—you can order as little as 5mg or 10mg per vial. Custom sizes are available, so just let us know what you need.
Lead time is usually 3-5 working days for in-stock items. If you need a custom packaging size, it might add a couple of days. We ship via express courier to the UK.
Yes, we include a COA with every batch showing the actual purity result—usually 99% or higher. You can also request additional documentation like an HPLC chromatogram if needed.
Keep it in a dry, dark place at 0-4°C for short-term storage, or at -20°C for long-term. Properly stored, it stays stable for over 2 years.
