Testosterone is the most common anabolic hormone:there is and is also considered the most basic. Due to this, bodybuilders often consider it the base steroid to most all cycles. Testosterone is both anabolic and androgenic in nature. Users of this steroid will notice a dramatic gain in muscle size and strength, as well as an overall sense of well being and increases libido and sex drive.
Testosterone aromatizes very easily:and therefore estrogen buildup and side effects can become an issue for users sensitive to these problems or those choosing to use a high dose of this compound. Therefore, when using Testosterone, bodybuilders often choose in incorporate an anti-estrogen such as Anastrozole, Proviron, Tamoxifen to help keep estrogen related side effects to a minimum. Extremely sensitive users, or users using very high doses (800-1200mgs) might find that stronger anti-estrogens such as Letrozole or Exemestane are more suitable. Androgenic side effects such as oily skin are also possible while taking Testosterone.
Bodybuilders looking to bulk up, often stack Sustanon with other steroids such as Deca 250 and/or Bold 200, along with an oral compound such as Methan or Oxy. Those Bodybuilders looking to use testosterone during cutting phase, might wish to stack it with compounds such as Trens, along with an oral like Stan or Oxan.
