So you're looking at Cagrilintide and Retatrutide for metabolic studies, and I'm guessing you've been through enough peptide suppliers to know the difference between a COA that's actually verified and one that's just a PDF someone made in Word — we've been shippng these to academic labs and private researchers for a while now, and most buyers go with the 10mg vials for dose-response work, though the 2mg is better if you're just doing preliminary binding assays.
The purity runs at ≥99% by HPLC, and we actually run a separate endotoxin test, which comes in under 0.1 EU/mg, so you're not going to get weird interference in cell-based assays form contamination, and the lyophilized powder dissolves cleanly in sterile water without any visible residue or clumping (usually 2-4 weeks for custom orders on the 5mg or 10mg vials).
We include the full HPLC trace and mass spec data with every shipment, plus the SDS and TDS if you need them for your institution's paperwork, and the MOQ is pretty flexible — we've done single-vial orders for small pilot studies and 50-vial lots for larger projects, though teh lead time on the latter is about 20 days or so.
One thing that catches people off guard is that the powder is hygroscopic, so once you open the vial, you really want to reconstitute it within a few minutes or it'll start picking up moisture from the air, which can shift the effective concentration a bit — it's not a dealbreaker, but it's something you'll want to note in your lab protocol.
Payment is standerd wire transfer or credit card through our portal, and we ship via FedEx priority with cold packs in insulated boxes, though if you're in a hot climate, you might want to request the dry ice option for summer months, as the peptide stability at 2-8°C is fine for transit but we've had a couple of packages sit on loading docks in Phoenix that got a little warm.
Anyway, we keep a fair amount of the 5mg and 10mg in stock for the Cagrilintide, but the Retatrutide we usually have to make to order, so confirm lead time before you schedule anything critical — COA will have the batch number and the actual purity value, which typically runs between 99.2% and 99.5% in our experience.
Our MOQ is 10 vials per compound, but we can do smaller custom orders if you're just starting a study. Just reach out.
We ship within 2-3 business days for orders under 100 vials, and we use cold shipping with ice packs to keep it at 2-8°C.
Yes, every batch comes with a CoA showing the HPLC purity and endotoxin levels, so you can verify it's under 0.1 EU/mg before use.
We ship them as separate lyophilized powders in individual vials per compound. If you need a custom blend, let's talk—we can do that for larger research orders.
Keep unopened vials at 2-8°C in the fridge. For long-term storage beyond 3 months, -20°C is best. Once reconstituted with sterile water, use it within 24 hours and don't refreeze.
Came across this supplier after extensive searching for specific research compounds. Communication was prompt and professional from the initial inquiry. The ordering process was straightforward, and I received a confirmation email with clear details almost immediately. Shipping was remarkably fast; the package arrived well within the estimated timeframe, which was a pleasant surprise given the nature of the products. The items were packaged with great care, ensuring discretion and integrity. Upon inspection, the vials were securely sealed and clearly labeled, reflecting a high standard of operational quality. While the intended use is strictly for laboratory analysis, the physical presentation of the compounds instills confidence in their purity as advertised. Customer service deserves a special mention for being both knowledgeable and responsive, addressing a minor logistical question I had without delay. Overall, this was a highly efficient and satisfactory transaction from start to finish. The combination of swift logistics, apparent product quality, and excellent support makes this source stand out for research purposes.
