Tadalafil (Cialis)

PDE5 inhibitor with a much longer duration of action than sildenafil — sometimes called "the weekend pill" — also approved at a low daily dose for ongoing use and for BPH symptoms.

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.

Reconstitution

Oral tablet; no reconstitution needed.

Storage

Store at room temperature.

Cautions

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.

Track Tadalafil (Cialis) in BioHack Track. Half-life, dose range and route come pre-filled from this library — log a dose and the app counts your vial down, models what is in your system, and puts it on the same chart as your labs and body composition.
