The prime advantage of this product is the fact that Testosterone Cypionate can be injected once per week and it gives some very good gains in strength and size. I would bet that many careers in bodybuilding and athletics were built with the long term use of this drug. I’ve used it at doses of 250-2,000 mg per week, and found that the best gains versus side effects are probably had somewhere below the 750 mg/week mark. Of course this is far below what many competitors in the upper ranks of bodybuilding use, but for the average (recreational) bodybuilder or athlete, the side effects above this dose do not constitute an acceptable trade off for the gains.
Androgens are responsible for the growth spurt of adolescence and for eventual termination of linear growth, brought about by fusion of the epiphyseal growth centers. In children, exogenous androgens accelerate linear growth rates, but may cause disproportionate advancement in bone maturation. Use over long periods may result in fusion of the epiphyseal growth centers and termination of the growth process. Androgens have been reported to stimulate production of red blood cells by enhancing production of erythropoietic stimulation factor.
