The real headache has been finding a GLP-1/GIP/glucagon triple agonist that actually stays stable through repeated freeze-thaw cycles, and most suppilers just don't get that. We've been burning through samples on that metabolic pathway work, and what it does is hold up better than the stuff we tested last quarter—HPLC and mass spec both verified it at 99% purity, which is tighter than the 97% we usually see.
So the white powder comes in 10mg vials, and you'll want to store it at -20°C desiccated or it'll degrade faster than you'd expect—roughly 20 days or so if left out. Solubility in water and common organic solvents is fine, but for the in vivo work, we're sticking with sterile saline because DMSO caused aggregation in our pilot runs.
Actually, the molecular weight isn't listed on the COA (the suplier says they leave that to the researcher to confirm), so you'll need to run your own ESI-MS if that's critical for your dosing. It's not ideal for receptor binding assays where exact molarity matters, but for the metabolic studies we're doing—glycemic control and weight management pathways—it's been pretty much spot on.
2381089-83-2 is the CAS, and the batch we ordered has a white powder appearance that looked clean under the loupe, no clumps or discoloration. Most buyers go with the 10mg size for the cell work, but for the animal studies, you'll want to check MOQ on larger amounts—we usually have stock, but confirm lead time if you need more than 50 vials at once.
We got COA and SDS with the order, and they include teh HPLC chromatogram and a mass spec trace, though the TDS only covers storage and handling basics without solubility optimization tips. One thing they don't tell you is that the peptide tends to absorb moisture if you open it in high humidity—so keep the desiccant pack in the vial until you're ready to reconstitute.
Our standard lead time is 3-5 business days for in-stock items. Custom orders may take 7-10 days depending on quantity.
Yes, the MOQ is 10 grams for Retatrutide. We can accommodate smaller research quantities on request.
We include an HPLC analysis report and mass spectrometry data with every batch. You'll get the full quality docs.
Store it at -20°C in a desiccated environment. Avoid freeze-thaw cycles and keep it sealed to prevent moisture absorption.
We can package in smaller vials or larger bulk containers per your request. Just let us know the specs when you order.
