You've been bouncing between suppilers trying to find consistent semaglutide that actually hits >99% on HPLC, and we've all been there — one batch looks fine, teh next one's got degradation peaks you can't explain.
The white powder comes lyophilized in 2mg, 5mg, or 10mg vials depending on what you're running, and the molecular weight sits at 4113.4 g/mol for the peptide backbone, though the full CAS 2023788-19-2 structure includes the attached fatty acid chain.
It basically holds up better than most GLP-1 analogs we've tested when reconstituted properly; we usually keep short-term stock at 2-8°C for about 20 days or so, but long-term it's stable at -20°C for over two years without noticeable loss.
What it does is mimic natural incretin pathway, but honestly, don't expect this to work in simple cell-free assays — it's designed for whole-organism or primary cell work where the full receptor signaling cascade matters.
One thing you might not think to ask: the vial fill volume is slightly over the labeled amount (typically 10-15% headroom) so you're not short when reconstituting, but confirm MOQ if you need custom labeling or bulk packaing.
Lead time runs about 10 working days for standdard orders, though we've had some ship in 5 when the lyophilizer cycle lines up right — just check current stock before placing if you're on a tight timeline.
Yes, every vial size — 2mg, 5mg, and 10mg — is filled from the same batch with >99% purity confirmed by HPLC. You get the same pharmaceutical grade regardless of which size you order.
We supply a Certificate of Analysis (CoA) with each order, showing the purity, identity, and molecular weight specs. If you need additional third-party testing reports or a material safety data sheet, just ask — we can provide those on request.
We don't have a strict MOQ — you can order as few as 1 vial if you're just starting a study. For bulk custom orders, we can accommodate any quantity; just let us know your required amount and we'll set it up.
Keep it at 2-8°C for short-term use (up to a few weeks), or at -20°C for long-term storage. Properly stored, it stays stable for over 2 years. Avoid repeated freeze-thaw cycles.
Yes, we can customize the vial labels with your lab's name, lot number, or any specific info you need. Just tell us the details when you place the order, and we'll handle it.
