The term "anabolic steroids" refers to testosterone derivatives that are used either clinically or by athletes for their anabolic properties. However, scientists have questioned the anabolic effects of testosterone and its derivatives in normal men for decades. Most scientists concluded that anabolic steroids do not increase muscle size or strength in people with normal gonadal function and have discounted positive results as unduly influenced by positive expectations of athletes, inferior experimental design, or poor data analysis. There has been a tremendous disconnect between the conviction of athletes that these drugs are effective and the conviction of scientists that they aren't. In part, this disconnect results from the completely different dose regimens used by scientists to document the correction of deficiency states and by athletes striving to optimize athletic performance. Recently, careful scientific study of suprapharmacologic doses in clinical settings - including aging, human immunodeficiency virus, and other disease states - supports the efficacy of these regimens. However, the mechanism by which these doses act remains unclear. "Anabolism" is defined as any state in which nitrogen is differentially retained in lean body mass, either through stimulation of protein synthesis and/or decreased breakdown of protein anywhere in the body. Testosterone, the main gonadal steroid in males, has marked anabolic effects in addition to its effects on reproduction that are easily observed in developing boys and when hypogonadal men receive testosterone as replacement therapy. However, its efficacy in normal men, as during its use in athletes or in clinical situations in which men are eugonadal, has been debated. A growing literature suggests that use of suprapharmacologic doses can, indeed, be anabolic in certain situations; however, the clear identification of these situations and the mechanism by which anabolic effects occur are unclear. Furthermore, the pharmacology of "anabolism" is in its infancy: no drugs currently available are "purely" anabolic but all possess androgenic properties as well. The present review briefly recapitulates the historic literature about the androgenic/anabolic steroids and describes literature supporting the anabolic activity of these drugs in normal people, focusing on the use of suprapharmacologic doses by athletes and clinicians to achieve anabolic effects in normal humans. We will present the emerging literature that is beginning to explore more specific mechanisms that might mediate the effects of suprapharmacologic regimens. The terms anabolic/androgenic steroids will be used throughout to reflect the combined actions of all drugs that are currently available.
For an easy point of reference, we have provided two charts below detailing the effects of steroids. We have listed the most common and popular anabolic steroids by their actual compound name and most popular trade name where such applies. While there are other steroids not mentioned, such steroids are extremely rare and will not be used by most individuals or even be available to them. Within the first chart, we have provided the score each steroid holds in-regards to muscle mass promotion, strength promotion, and cutting effect. The three categories are all measured on a scale of one to ten (1-10); it should be noted, just because a steroid has a lower score does not mean it’s worthless; it simply means other steroids perform the specific action with a higher score. Further, in the second chart, each steroid is also listed in accordance to classification; testosterone or dihydrotestosterone based, 19-nortestosterone, and labeled by its aromatizing or progestin nature as well as hepatotoxicity; this will guide you along as it pertains to side-effects by referencing the negative effects of steroids discussion above. For our female friends, we have also included virilization scores; this time with a high, moderate to low ranking. In the second chart, each steroid is simply listed by its most commonly used name.
Testosterone is one of the highly used steroids that is the combination with both androgenic and anabolic at a ratio of 1:1. That’s why it is on the list of most balanced steroids. Testosterone available in different chemical forms which makes it quite popular among the users. Some varieties of testosterone includes- testosterone propionate, testosterone undecanoate, and testosterone enanthate and testosterone cypionate. It is very common among the athletes using testosterone as their steroid cycles and also for the post steroid cycle. Since this steroids making natural testosterone in human body, so it is in the list of best steroids cycles .
