The molecular weight sits around 4.1kDa, which is actually on the larger side for a peptide—makes it a bit different form some of the smaller GLP-1 agonists we've handled, and solubility in water at 5mg/ml is decent for most reconstitution work we see.
We're getting it as a, purity verified at 99% or better by HPLC, and storage is straightforward at -20°C—basically standerd freezer conditions, but we usually have stock and confirm lead time is 20 days or so.
What it does in practice is act as a triple receptor agonist, hitting GLP-1, GIP, and glucagon pathways, which is why most buyers go with it for weight management research rather than just glucose control—it's not suited for acute metabolic studies where you'd want a single-target compound.
CAS number is 2381089-83-2, and you'll see it listed as LY3437943 or Retaglutide on some COAs—the acetate salt form is what we're getting, and the packaging is safety-packed dry ice shipment (usually 2-4 weeks lead time if we're out of stock).
One thing a buyer might not think to ask: the lyophilized cake can be fragile if shipped in hot weather, so we double-check teh transport packging for insulation—better than reagent grade for this kind of stability-sensitive peptide.
Anyway, it's for research use only, not human consumption, and the MOQ is typically 10mg or 50mg depending on batch availability—check COA for exact purity data since it varies slightly batch to batch.
Our standard MOQ is 10 grams for bulk orders, but we can discuss smaller quantities depending on your research needs. Just reach out to us directly.
Lead time is usually 7 to 14 business days after payment confirmation, depending on the order size and current stock. We keep safety stock to avoid delays.
Yes, a COA from our in-house lab is included with every batch. Third-party testing reports are also available upon request for full transparency.
It comes in a sealed, vacuum-packed vial inside a padded safety package with ice packs to maintain -20°C conditions during transit. All shipments are discreet and temperature-monitored.
No, we only supply the lyophilized powder—custom formulations or pre-mixed solutions aren’t available. You’ll need to reconstitute it with sterile water in a lab setting.
