The vial and the pen: how they fit together

Every research compound on our menu is supplied as a lyophilised vial. The vial is the product: it holds the batch-verified compound, freeze-dried for stability, ready to reconstitute to your own protocol.

The reusable injector pen is sold separately and ships empty, with no research compound inside. It is a click-calibrated device you pair with a reconstituted vial when you want consistent, repeatable measurement across your work.

In other words, you always order the vial for the compound itself. The pen is optional hardware: order one if you don't already run your own dosing device, and reuse it across future vials.

You can add a vial and a pen to the same order, or order the vial on its own.
