How it works
It binds androgen receptors strongly, does not convert to estrogen, and is one of the harshest 17-alpha-alkylated steroids on the liver.
Half-life: about 9 hours.
Release profile
How levels rise and fall after a single dose, based on a half-life of about 9 hours. Each mark on the axis is one half-life; after about five, almost none is left.
An illustration from the half-life only; real levels vary with dose, food, how quickly it is absorbed and the person.
Clinical reference dose
Clinical reference: the Halotestin label used 5–20 mg a day for low testosterone and 10–40 mg a day, in divided doses, for breast cancer.
It is known for aggression and liver strain even at modest doses.
These are reference amounts from labels and clinical studies, not a personal recommendation. A doctor sets the right dose for you, using your bloodwork.
