our company can run these in custom vial sizes and concentrations—just tell us what you need for your study, and we'll adjust the batch synthesis accordingly, labeling included.

You press it against the skin and it does teh rest, with a click and a flash to confirm the dose is delivered, basically foolproof for anyone handling it.

The dimensoins are roughly 18 by 18 by 145 millimeters, give or take a few on length depending on needle gauge, and it handles fluids up to 20cP viscosity, which covers most peptide solutions.
Most buyers go with the 27G or 29GTW needle for retatrutide, but we can swap to smaller if your protocol demands it (check lead time on custom needles).

What it does is hide the needle completely before and after use, so there's no accidental sticks—a detail that matters more than you'd think in a busy lab.

We usually have stock on the 1ml and 2.25ml capacities, but if you need something outside that range, customiztion is where we shine, and lead time is typically 20 days or so.
