The purity consistently exceeds 99.8% by HPLC, which is teh really important number here, because that means very minimal truncated peptide fragments — those are biggest source of variability in triple agonist studies.
It's lyophilized form a phosphate buffer that keeps the aggregation pretty low during storage, but once you reconstitute it, you've got maybe 12-24 hours before things start degrading even at 4°C.
Most buyers go with the 10mg vials for dose-range finding, since you don't need a ton of materail to see if the GIPR agonism is synergizing with the GLP-1 effect in your model.
(usually 2-4 weeks lead time) on custom vial sizes, but we keep 10mg and 5mg in stock if you need it fast — just check the COA for the exact residual solvent ppm, which varies slightly between batches.
It's not great for acute metabolic studies that last less than 48 hours — this peptide was designed around once-weekly dosing in vivo, so the pharmacokinetics favor sustained receptor activation over quick pulses.
The molecular formula C172H265N43O51 runs heavy at about 3826 g/mol, and what that means in practice is that standdard RIA kits calib GLP-1 analogs cross-react unpredictably, so you'll want to run your own spiking controls.
Our standard MOQ is one box (10 vials), but we can sometimes accommodate smaller orders depending on your research needs. Just contact us to check availability.
Yes, we supply a COA with each batch that confirms the purity and other specs like appearance and molecular weight. Request it with your order and we'll include it.
Store it at -20°C or below, ideally in a freezer. Keep it sealed and away from moisture — that's key to maintaining that >99.8% purity for your research.
We typically ship in 10-vial boxes, but if you need a different package size for your study, let us know. We'll see if we can adjust it for you.
For UK orders, lead time is usually 5-10 business days after payment, depending on customs. We use tracked shipping so you can follow it all the way.
