    99%Min Purity Testosterones Base for Bodybuilding


    Testosterones Base belongs to the class of androgensIn fact this is the main androgenic hormone in the body. It is a very powerful hormone and Testosterones Base is largely responsible for the development of the testicles and prostate, as well as development of muscle tissue, bone density and strength.

    Beyond these basic functions, Testosterones Base is essential to our health and general well-being.

    De low levels of Testosterones Base can not only negatively affect muscle strength and bone density, but can also affect our mood.


    Although part of the androgen class of steroidal hormones, Testosterones Base is also strongly anabolic.


    Both anabolic and androgenic, Testosterones Base is like all steroid hormones, is derived from cholesterol and its natural production is largely regulated by the luteinizing hormone (LH) and follicle stimulating hormone (FSH).

    For these hormones are released, the pituitary gland must first be driven, and once LH and FSH are released, the stimulation of the testis is obtained, thereby causing the production of Testosterones Base.

     As you can see, important though the testes in the production of Testosterones Base, the pituitary gland is also a key. Without normal functioning of the pituitary gland (in the brain), the natural production of Testosterones Base can not do.

    Usage of  Testosterons Base: 

    Applies to male sexual inadequacy, sex organ dysplasia, infertility, cryptorchidism and infertility. Can also be used for female functional uterine bleeding, climacteric syndrome, breast cancer and genital cancer; liver cirrhosis, aplastic anemia, osteoporosis and other wasting disease. 

    Testosterone enanthate exhibits a strong androgenic effect and good anabolic characteristics as well. Primoteston combined with other steroid compounds, is the most common stack used in the bodybuilding community, and will give great results in almost every case.
