So the researchers your client works with—they're running dose-response studies on metabolic regulation, and they need the peptide to consistently trigger that GLP-1 and GIP receptor activation across multiple assays, which means purity has to hold up at 99% or better or the data gets muddy.
we ship—it's stored at -20°C form our end, protected from light obviously, and we send COAs with every batch from HPLC plus MS and Janoshik testing—pretty standdard for research-grade stuff.

Typical order is 10, and the 60mg size is popular among labs running chronic dosing protocols, but the 5mg or 10mg vials work fine for acute studies.

One thing to watch out for is that solubility's only slightly soluble in water—DMSO's your better bet for reconstitution if you're injecting into saline later, and most buyers go with the 15mg for the balance of cost and per-vial volume.

Shelf life is 24 months when stored properly, so if you've got a batch sitting at room temp for weeks it's basically useless, but we usually have stock and lead time is about 15 days or so depending on order volume.
GMP standard production but don't expect this to work for anything beyond research—it's not formulated for human use, and teh 10mg vials have tighter purity specs than some competitor stuff we've seen.
We don't have a strict MOQ — you can order as little as 1 vial. But if you're buying in bulk, we can offer better pricing on larger quantities.
Most orders ship within 1-3 business days after payment confirmation. For bulk orders, it might take a bit longer depending on stock and shipping method.
Yes, every batch comes with a COA from our in-house QC, and we also use third-party Janoshik testing to confirm the 99%+ purity. You’ll get both reports with your order.
We currently offer 5mg, 10mg, 15mg, 20mg, and 60mg vials, packed 10 vials per box. Custom packaging or other sizes aren’t available for this product right now.
Store it at -20°C in a freezer, away from light. If kept properly, it stays good for 24 months. Avoid repeated freeze-thaw cycles to maintain potency.
