Anabolic steroids differ in their characteristics, which means there are steroids that are only suitable for specific uses. For instance, Trenbolone is not recommended for bulking but it is an outstanding fat burner. This makes it perfect for a lean mass cycle or a cutting cycle. Always take the side effects of a particular compound into consideration whenever you plan a stack. Do not combine anabolic steroids that show similar side effects. For example, never combine Anapolon and Dianabol because they are already quite toxic and if you combine them, the toxicity will increase exponentially and cause serious damage to your body.
Lastly, all anabolic steroids are known to be suppressive to the HPTA (Hypothalamic Pituitary Testicular Axis), which results in a suppression and/or total shutdown of endogenous natural Testosterone production. This is one of the reasons why cycles must be kept as short as possible, as the longer a cycle is run the more difficult it is for one to restore their endogenous production of hormones. D bol is very well known for its strong suppressive nature. Studies have been conducted on Dianabol’s suppressive nature in particular, and they have demonstrated that doses as low as 15mg per day for 8 weeks caused mean plasma Testosterone levels to decline by 69%  . It is very important that following any cycle, the user engages in a Post Cycle Therapy (PCT) program, which includes the use of Testosterone-stimulating compounds (such as Nolvadex ) for a 4-6 week period in order to ensure full restoration of the body’s endogenous production of Testosterone and related hormones. Without a proper PCT program, the user risks damaging and/or shutting down his HPTA for the rest of his life.
The Dianabol utilization intensifies the sebaceous glands because it has a strong androgen component which is converted in dihydrotestosteron; this side effect causes for some athletes acne on the face, on the neck, on the thorax or on the shoulders. In case of a hereditary predisposition, the Dianabol can accelerate the baldness because of the same thing: its transformation in dihydrotestosteron. The Dianabol action effect is significant for the endogen testosterone. The investigations demonstrated that a 20 mg daily dose can diminish the testosterone production level in the organism with 30-40% after only 10 days of use.
