This is 120 units, past the 60-unit dial. Splitting it across administrations, or using less water to raise the concentration, brings it back into range.

Dial range varies by pen; 1–60 units is the common configuration.

The concentration is the line worth having: a vial two weeks later carries no record of how much water went into it.

Published research contexts for TB-500 describe 2–5 mg per administration. Descriptive only, not a recommendation.

Modelled level — 2x per week

Levels read as multiples of a single administration's peak.

Steady-state peak: 1.65× single dose
Time to steady state: 12.5days
Administrations: 2/ week
