So far, only the substance known as “SARMs S4” (ANDARINE S4) has made it to the market, used by a limited number of professional and amateur bodybuilders.

The Gene Follistatin (FS344)

The road to big, strong muscles is long and requires hard work in a gym. But researchers may have found a shortcut where muscles grow on their own. Scientists have actually succeeded in increasing lean body mass and strength in macaque monkeys using gene therapy. The experiment was quite simple: the researchers injected the gene follistatin (FS344) directly into the monkeys’ right thigh muscles.

Follistatin was shown to block myostatin, a molecule that downregulates muscle growth but strengthens tendons. Eight weeks after the injection, the circumference of the monkeys’ right thigh muscles had increased by an average of 15 percent compared with the left thigh. A study conducted on two of the monkeys showed that muscle strength in the right leg had increased by 12 and 36 percent, respectively, compared to the untreated leg!
