Sustanon is a very popular steroid that is highly valued by its users, as it has several advantages over other testosterone drugs. Sustanon is a mixture of four testosterones, which, due to a certain structure, have a synergistic effect. This feature entails two positive qualities of interest to athletes. Based on the special interaction of active chemicals, Sustanon milligram per milligram has a better effect than testosterone enanthate, cypionate and propionate. In addition, the effect of these chemicals is also temporarily in succession, so that Sustanon begins to act quickly and at the same time remains effective in the body for several weeks, thanks to the propionate contained in Sustanon.
