TESTOSTERONE-P is an oil-based solution of Testosterone Propionate for IM injection delivering testosterone in case where rapid dose titration and rapid clearance are desirable. It is used for androgen replacement therapy in conditions associated with deficiency or absence of endogenous testosterone. Testosterone is responsible for the development and growth of the male sexual organs and post-adolescent secondary sex characteristics. Androgen effects include but are not limited to the maturation of the penis, scrotum, prostate, seminal tubules, laryngeal enlargement, vocal cord thickening, changes in muscle mass and fat distribution, and the development and distribution of male hair (facial, pubic, chest, back, axillary).
