We usually keep decent stock of the 10mg and 15mg vials, but the 30mg can sometimes take 20 days or so if we're waiting on a production run — definetly check lead time before placing a big order, especially since we ship it on dry ice with a cold chain monitor included in teh box.
It's a lyophilized powder, white, and you'll want to store it at -20°C protected form light, which is pretty standdard for peptides like this, and the shelf life is over two years if you don't mess with the temperature; once reconstituted in DMSO, it's stable for about a week if refrigerated.
Most buyers go with the 10mg vials for pilot studies because they're easier to aliquot, but the 30mg is better if you're running larger rodent trials and don't want to reconstitute multiple vials every day — purity runs above 99% by HPLC, which matters for consistent.
Actually, one thing people don't always think about: this peptide has a molecular weight of 4813.45 g/mol, so when you're calculating molar concentrations for your receptor binding assays, make sure you're not using a calculator set for smaller peptides, because that'll throw your numbers off.
It's not suited for anything involving oral dosing in research, since it degrades in the GI tract pretty quickly, and we see most labs using it for metabolic studies in mice or rats where they need dual GLP-1 and GIP receptor activation, but I wouldn't recommend it for acute toxicity screens because the half-life is long and can muddy your data.
Anyway, we've had a few researchers ask about the CAS number — 2023788-19-2 — and that checks out fine with customs for the HS code 2934.99.9001, though we always include the SDS and COA with each order just to keep things smooth.
We don't have a strict MOQ — you can order just one vial if you want. Bulk discounts kick in at 10+ vials, so let us know if you need a larger quantity.
Yes, a COA is included with every shipment. It shows the HPLC purity (>99%) and confirms the identity and molecular weight, so you know exactly what you're getting.
We currently stock 10mg, 15mg, and 30mg vials. If you need a custom size, reach out to our sales team — we can arrange it for bulk orders.
Keep it at -20°C in a freezer, and protect the vials from light. Properly stored, it stays stable for over 2 years. Avoid repeated freeze-thaw cycles.
For in-stock items, we ship within 1-2 business days. International orders usually arrive in 5-10 business days depending on customs. Rush shipping is available if you need it faster.
