High Purity Polaris Peptides - Retatrutide, Cagrilintide, GHK-Cu & More for Research Use

We've got this batch of Polaris Peptides in stock right now, so lead time is usually a few days for standard orders—just confirm the volume and we'll give you a shiping window (typically 2-4 weeks for internatioanl cold chain). 2. Teh 2mg, 5mg, and 10mg vials are what most buyers go with, and the lyophilized powder is straightforward to reconstitute in water or buffer, though I'd recommend sterile technique since it's been sterile filtered. 3. Purity checks out at ≥99.5% by HPLC and MS, which is better than reagent grade for this kind of work, and we've handled enough of these to tell you the white powder holds up well at -20°C long term. 4. One thing to keep in mind is that these aren't suited for anything beyond research use—no clinical application here, and the CAS numbers vary per compound, so you'll need to match them to your protocol. 5. We usually have individual COAs on file for each lot, and the molecular weights and formulas are compound-specific, so just ask if you need the specs for a partciular one. 6. It's pretty much a standard peptide setup, anyway—no surprises with solubility, and the cold chain packging is enough to handle transit without degradation.
