Test E 300mg is a slow-acting injectable form of the androgen testosterone. It delays relatively less water than Sustanon and its analogues, which in turn affects the quality of the increase in dry muscle mass.
It is used for the purpose of treating hypogonadism and andropause, in which adult males produce inadequate levels Testosterone endogenously.
It is also used in the breast cancer treatment for females as well as delayed puberty in male teenagers and for pubertal stimulation.
A weekly dosage of 200mg had effectively reduced the production of sperm in the majority of men, although 3 months of consistent use was required before significant changes in sperm production and motility were seen. This suppression of spermatogenesis was shown to remain for as long as Testosterone Enanthate was administered, and slowly returned to normal following termination of use.
