Steroid effects on muscle fibers

The purposes of this investigation were to examine the effects of anabolic steroid treatment on protein synthesis in skeletal muscle and on steroid receptors. The experiments were conducted with 230 male albino rats maintained on a diet containing 20% protein. Anabolic steroids (methandrostenolone, methylandrostendiole, and Retabolil) were injected in doses of mg/kg body weight. The animals were examined at rest and after swimming exercise of 15 min duration. Quadriceps and gastrocnemius muscle were used for analysis in all experiments. Protein synthesis was studied by means of 14C-leucine incorporation. It was found that anabolic steroid treatment resulted in an increased content of skeletal muscle protein: myosin, myofibrillar, and sarcoplasmic fractions. The activity of RNA-polymerase in skeletal muscle nuclei was increased. The results indicated that in skeletal muscle there were androgen receptors which were binding sites for 3H-testosterone and anabolic steroids. A model for the anabolic steroid action on the regulation of protein synthesis in skeletal muscle was proposed.

However, the Anavar steroid was discontinued by Searle in 1989, due to the bad press brought on by bodybuilders abusing the drug. It was later reintroduced to the world market as Oxandrin in 1995, but it remains a controlled substance under US law. The current manufacturer of oxandrolone holds all the rights to their medicine, and that’s why it is very rare to find oxandrolone today. It’s still called Anavar by most people, and it’s very hard to buy. Even if you do find Anavar for sale, the law of supply and demand inevitably results in a rather exorbitant price for the steroid.
