In the blood, approximately 98% is coupled with plasma proteins – 40% with albumin and 58% – with globulin. Mesterolon is rapidly metabolized. It is eliminated with urine only as metabolites. The basic metabolite is 1B-methyl-androsterone in conjugated form, which constitutes 55-70% of metabolites eliminated with urine. Another metabolite is 1a-methyl-5a-amdrostan-3a, 17B-diol, constitutes about 3% of metabolites eliminated with urine. About 80% of the administered dose is eliminated in the form of metabolites with urine, and about 13% – with feces.
