Premium Paramount Peptides Retatrutide Lyophilized Powder for Research Use

We've been moving this particualr peptide for about 18 months now, so I can tell you the purity consistently runs above 99% on the HPLC, and the lyophilized cake is that classic white solid you'd expect — it reconstitutes cleanly in water or sterile saline within a minute or so with gentle swirling.

The molecular weight is 3849.3 g/mol, which is on the larger side for a triple agonist, so the solubility is actually better than some of teh earlier analogs we handled. You'll want to store it at -20°C in the lyophilized form, and under those conditions it's stable for 24 months or so. One thing buyers sometimes don't think about is that even brief exposure to room tempearture isn't catastrophic, but we don't recommend it for more than a few minutes during handling.

Basically, this isn't suited for anything beyond receptor activation studies and metabolic work — it's not something you'd use in a cell proliferation assay without checking cross-reactivity first, because the triple agonist profile (GIP, GLP-1, GCG) can muddy your results. We usually have stock of the 2mg and 5mg vials, but the 10mg size is actually more popular for. The packaing is sealed under inert atmosphere, so you don't have to worry about oxidation during shippng.

The CAS number is 2381089-83-2, and our company provide a full COA with every shipment — chromatograms are pretty clean, typically showing a single peak at about 99.2% or so. Lead time is usually 2-4 weeks for standard orders, but if you need it faster, we can sometimes expedite for a small fee. Just confirm your MOQ when you send the RFQ, and we'll get you a quote within 24 hours.
