Injectable steroids are injected into muscle tissue, not into the veins. They are slowly released from the muscles into the rest of the body, and may be detectable for months after last use. Injectable steroids can be oil-based or water-based. Injectable anabolic steroids which are oil-based have longer half-life than water-based steroids. Both steroid types have much longer half-lives than oral anabolic steroids. And this is proving to be a drawback for injectables as they have high probability of being detected in drug screening since their clearance times tend to be longer than orals. Athletes resolve this problem by using injectable testosterone early in the cycle then switch to orals when approaching the end of the cycle and drug testing is imminent.
Deca-Durabolin is the most widely spread injectable steroid. Its strong anabolic effect and the insignificant androgenic compound offer a good gain of muscle mass and strength, without any pronounced side effects. The recommended dose for Deca-durabolin is 200-600 mg weekly. The best result is obtained when using 4 mg per 1kg. Deca-durabolin is usually combined with other substances in order to get the wanted result. For defining and striation, it can be combined with 10-20 mg of Winstrol (or Halotestin or Trenbolone) daily. For muscle mass gaining, it combines perfectly with Danabol (300-400 mg of Deca and 20-30 mg of Danabol is a classic cycle), Anapolon or Testosterone.
To strengthen the anabolic properties of testosterone, more than 100 synthetic steroid derivatives have been described for human purposes. The anabolic effect promotes protein synthesis, muscle growth and erythropoiesis. In clinical practice, substances with anabolic effect are needed to overcome various catabolic states. However, none of these compounds are devoid of androgenicity. Androgenic and anabolic properties of anabolic steroids cannot be totally separated. Therefore, it is more appropriate to use the term anabolic androgenic steroids (AAS).
