the mechanism

Two chambers. One twist.

Peptides are fragile once they are in solution. The powder stays dry in one chamber; the liquid stays sealed in the other. The twist opens the seal and the two meet minutes before the first click.

The click is set by your dog's weight band. There is no vial to draw up and no unit math at the counter. That is the whole design argument: a daily protocol that gets finished.
