TRENBOLONE-E is an oil-based solution of Trenbolone Enanthate for IM injection, delivering trenbolone in case where prolonged dose titration and slow clearance are desirable. Endogenous androgens such as trenbolone or derivatives are 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).
