We’ve been handling this peptide for years, and most buyers go with the 10mg or 20mg vials for standard work—custom sizes form 2mg up to 50mg are no problem, but we usually have stock on the common ones. 2. It’s a white powder, ≥99% purity by HPLC, and you’ll want to keep it at -20°C in a dry enviroment; shelf life is 24 months if stored right, though we’ve seen it hold up longer in practice. 3. Bulk pricing depends on quantty and size—orders over 100 vials typically get a better per-unit rate, but confirm lead time (usually 2-4 weeks for custom sizes). 4. Every batch gets a COA with mass spec data, so you can verify specs yourself—we don’t hide raw numbers. 5. One thing buyers don’t always ask: the vials are sealed under inert gas, which helps prevent moisture degradation during shiping. 6. This isn’t for anything beyond research use—no human or animal appliction, and we’re upfront about that.
We can do single vials for most sizes, so no strict MOQ on the 2mg — but for custom sizes between 2mg and 50mg, we usually ask for a minimum of 10 vials per batch to keep production efficient.
Yes, every batch comes with a CoA that shows HPLC purity results. Just ask when you place your order, and we'll include it with the shipment.
We ship the lyophilized powder in sealed vials with desiccant, packed in insulated containers with ice packs. For long transit, we recommend using a cold chain service to keep it at -20°C.
We can fill custom sizes between 2mg and 50mg per vial, including 8mg. Just give us the exact mg per vial and total quantity, and we'll adjust the fill accordingly.
For the 50mg size, standard lead time is about 5-7 business days after order confirmation, since we may need to synthesize a fresh batch. Smaller sizes are often ready within 2-3 days.
