High Purity Prime Peptides Retatrutide CAS 2381089-83-2 for Research Use

Actually, the main thing to know upfront is that this is strictly for research use only — it's not formulated or tested for anything clinical, so if you're running anything beyond in vitro or in vivo lab models, this isn't the right material.

For metabolic studies it's pretty much ideal for us because of that it hits three receptors at once — GLP-1R, GIPR, and GCGR — and we routinely see HPLC purity above 99%, which gives us tighter tolerance than most peptide research tools when we're doing receptor binding assays.

that dissolves readily in water, so reconstitution is straightforward, but you'll need to store it at -20°C protected from light (usually 2-4 weeks of room temperture stability, but check lead time on your freezer space).

CAS is 2381089-83-2, molecular weight comes out to about 3828.2 g/mol — we've been getting consistent COAs showing >99% purity on each batch, and teh shelf life is listed as 24 months when kept under those conditions.

One thing I noticed is that the molecular formula is C172H265N43O51, which is fairly large for a peptide (3828.2 g/mol), so make sure your balance can handle that for accurate dosing — most buyers go with the 5mg or 10mg vials depending on their typical batch size, and we usually have stock but confirm lead time.

So we're ordering form suppiler who did our last batch, no markups or middlemen, and it come with a full HPLC trace on every lot — also, they mentioned it's not suited for anything beyond research grade, which matches our protocol requrement anyway.
