Testosterone Mix or Sustanon is one of the most popular and used anabolic steroids. Sustanon acts from the first administration due to the testosterone propionate in the composition. The other esters in the composition have a long action of 1-2 weeks. It is a better steroid because of its enanthate or cypionate testosterone because it maintains a constant level of testosterone in the blood. It has a high anabolic effect and also a pronounced androgenic activity. It is a steroid used during periods of mass accumulation, brings significant gains in mass and strength. Although it is flavored as a testosterone-based steroid, its side effects are milder than those of enanthate testosterone. Sustanon will be felt quickly in the body due to the short esters that start acting immediately after injection.
