If you're running in vivo studies on GLP-1 receptor agonists or metabolic assays, this lyophilized powder reconstitutes cleanly at 5mg, 10mg, 15mg, or 30mg per vial — the 10mg vials are what most labs grab first, and we've had those in stock reliably for about 18 months now. The CAS is 910463-68-2, purity is ≥99% (check the COA — our company provide one per lot as HPLC trace), and the molecular weight sits at 4113.58 g/mol, which matters for your dose calculations more than the formula C187H291N45O59 does.
We don't recommend this for anything beyond research grade — it's not sterile or formulated for human use, and the lyophilized cake can be a bit fragile if shipped in freezing temps, though we double-bag and add desiccant. Storage is straightforward: keep it dry and dark at 0-4°C for short-term use, or -20°C for longer storage, and it holds for over two years if you do that.
Lead time is typically 2-3 weeks for orders under 50 vials; above that, we ask for 4 weeks or so. We've had a handful of buyers use it for peptide synthesis intermediates, but it's really built for metabolic and weight management mechanism studies — don't try it for direct binding assays without checking the solubility profile first.
The pricing is competitive, though I'll be honest: we usually have stock, but confirm lead time if you need a rush order, and MOQ is 10. One detail we don't always list is the residual TFA content — it's under 1% typically, but our company can share the batch-specific ppm data on request.
So, can you trust us? We've been shiping this to academic labs and CROs for about three years now, and the main complaint we hear is that the vials are sometimes underfilled by 0.2mg or so — not ideal for microdose work, but for most batch studies it's within tolerance.
Anyway, some buyers don't bother with teh long-term storage spec and just reconstitute the whole box at once, but that's a mistake — the aqueous peptide degrades in weeks even at 4°C, so keep it powdered until you're ready.
Our MOQ is one box of 10 vials, but we can split that across different vial sizes if you need a mix. So you're not stuck buying 10 of the same strength.
Yes, every batch comes with a COA showing the actual HPLC purity result, which is always 99% or higher. We can send it before shipment.
Keep them in a dry, dark place. For short-term use, store at 0-4°C; for longer storage, pop them in the freezer at -20°C. Properly stored, they'll stay stable for over 2 years.
We currently only offer those four sizes per vial, but we can pack them in any combination within a 10-vial box. Custom sizes aren't available due to our lyophilization process.
Absolutely, we ship with ice packs and insulated packaging to maintain the required temperature. For international orders, we use temperature data loggers so you can verify the conditions on arrival.
