BioHack Track models Tadalafil (Cialis) at a half-life of 17.5 hours, so every dose you log is decayed against that curve and the app shows what is still circulating — not just what you typed.

Store at room temperature.
Prescription medication. Same nitrate interaction warning as other PDE5 inhibitors; its long half-life means side effects (headache, back pain, flushing) can also linger longer.
