We've been running this peptide through our lab for a while now and the purity consistently hits above 99% by HPLC, so it's pretty much the standerd for metabolic research if you're looking at GLP-1 receptor agonists—most buyers go with the 10mg vial for longer studies.
What it does is basically bind to teh GIP and glucagon receptors alongside GLP-1, which gives you a broader metabolic effect than just weight loss alone, and molecular weight is roughly 4.1 kDa (soluble in water or bacteriostatic water, no DMSO needed).
Storage is straightforward: keep it at 2-8°C unreconstituted, and for long-term it's better at -20°C, but we usually have stock on the 1mg, 2mg, and 5mg vials—the 10mg sells out faster, so confirm lead time if you need that size.
50 units or so is the typical MOQ for smaller labs, but our company can do custom batches if you're running high-throughput screening (lead time is about 20 days or so).
It's not ideal for in vivo work unless you're set up for sterile handling since it's non-sterile research grade, but for binding assays or cell-based studies the lyophilized powder reconstitutes easily.
Also, you'll want to check the COA for each batch because we verify by MS as well, and the appearance is off-white powder (nothing fancy, but it's consistent batch to batch).
Our Retatrutide is ≥99% pure, verified by HPLC and mass spectrometry. You'll get the quality specs with each batch.
We offer 1mg, 2mg, 5mg, and 10mg vials. MOQ is typically 10 vials per size, but we can discuss larger custom orders.
Keep the lyophilized powder at 2-8°C for short term, or -20°C for long term storage. Once reconstituted, use immediately or store at 2-8°C for a few days.
No, it's non-sterile research grade only—not for human or veterinary use. Always handle with proper lab gear and equipment.
Orders ship within 1-3 business days. Since it's lyophilized, we send it at ambient temperature—no cold shipping needed. Expect 5-10 days for delivery depending on location.
