We've got this one in stock right now, so lead time is usually 3-5 business days if you order off teh shelf — but check before you place a large bulk order. The cold chain shiping is handled with insulated packging and ice packs, so small quantities (5-10 vials) arrive just fine.

It's a lyophilized powder, not a tablet, and pretty much exclusively for research use — don't expect anything clinical or human-ready. Most buyers we see are running in vitro studies or early animal work, and the 10mg vial (1mg per box, since it's 10 vials) is a common starting point.

Purity runs at 99% or better by HPLC, which is tighter tolerance than some research-grade peptides we've seen on the market. We store it at -20°C for long term; 0-4°C is fine for 20 days or so. The shelf life is over 2 years when kept dry and dark.
The 5mg, 10mg, and 15mg per vial options let you scale up without ordering huge boxes — but honestly, if you need something for long-term stock, the 15mg vials work better because you reconstitute less often.

Also, we don't ship this with a COA in the box automatically; you have to request it, and we'll email a PDF (usually within 24 hours). It's a small thing, but researchers ask about it more than you'd think.

What it does is offer competitive pricing on retatrutide itself, but the real value is that we handle bulk discounts from 50 vials up; we've done 200-vial runs for labs without issues. Anyway, just confirm your quantiy and we'll quote the price per vial.
Yes, you can mix sizes in one bulk order. The discount applies to the total quantity, not per size—just let us know the breakdown when you place the order.
Absolutely, we include a COA with every batch. It details the purity, identity, and other QC results so you can verify the ≥99% spec.
Lead time is usually 5–10 business days for bulk orders, depending on volume and current stock. We'll confirm a precise ETA after you place the order.
Yes, the bulk discount kicks in at 50 vials or more. You can mix sizes to hit that MOQ.
Keep it dry and dark—short term at 0–4°C is fine, but for long-term storage, -20°C is best. Properly stored, it stays stable for over 2 years.
