We’ve handled hundreds of kilos of this stuff, and honestly the 99%+ HPLC purity is consistent—it’s the main reason researchers keep coming back for metabolic studies, especially GLP-1 receptor work. You’re looking at a white frozen powder that basically disappears once you reconstitute it with sterile solvent, so make sure your buffer’s ready.
The molecular weight’s roughly 771.9 g/mol, CAS 129954-34-3, and it’s a C33H57N11O9 peptide that’s pretty sensitive to tempearture—store at -20°C long term or 2-8°C after reconstitution, and it’ll hold for about 20 days or so. Most buyers go with 10mg vials because the dosing is easier to work through, but we’ve got other research quantities available too.
It’s not great for anything oral—this is strictly injection-grade after reconstitution, so don’t expect a pill form. The quality control includes HPLC, MS, and a COA —we’ve had labs run it against reference standard and it usually hits 99.2% or better, which is tighter tolerance than most generic suppliers can claim.
One thing that catches people off guard: the powder can clump slightly during shipping if temperatures fluctuate, but a brief warm-up to room temp fixes it just fine—no loss in potency. We don’t include the solvent (check lead time), and the 5L drum packging is easier to handle for larger studies, but the standard 1g or 100mg options are more common.
Anyway, lead times are usually 2–3 weeks depending on quantty, and we’ve got about 50 units or so in stock right now, though that shifts weekly. You’ll want to confirm your preferred pack size and whether you need a full COA package with the order—most labs just ask for the certificte by email after purchase.
