BioHack Track models Finasteride (Propecia) at a half-life of 5.5 hours, so every dose you log is decayed against that curve and the app shows what is still circulating — not just what you typed.
Oral tablet; no reconstitution needed. Topical/oral compounded versions also exist.
Store at room temperature.
Prescription medication. Small risk of sexual side effects (some persisting after discontinuation in rare reports — "post-finasteride syndrome" is debated); not for use by women who are or may become pregnant.
