This SARM was initially formulated as a male contraceptive. It caused a reduction in spermatogenesis and boosted libido in men.

Experiments have been conducted on mice with Andarine S-4 which have shown positive results. It helps build lean muscle mass and boosts calcium levels. This is a must for bone density growth and lean muscle mass build-up.

Progressively positive results on mice have opened up new avenues to be explored with this SARM.

How does Andarine S-4 function?

SARMs are one of the three synthetic substances that respond to the androgen receptors present in the body. The other two compounds being:

The principal substance/AR antagonist which connects and combines to the receptor present in the body to prevent reactions. This then combines and ties to the receptor and then recombines. This process is repeated many times.

The presence of an AR agonist which combines to the cell receptor and subsequently reacts freely.

Andarine S-4 binds to androgen receptors and stimulates the effects of testosterone on the body like improving muscle and bone development. It does so by creating an anabolic environment in the muscle tissues. This synthesized protein as a result of the reaction allows the growth of muscles. Andarine S-4 is devoid of negative symptoms as shown by anabolic steroids, however it has very similar beneficial effects. To summarise, andarine S-4 can be called a SARM which aids muscle development via its androgenic impacts.

Main benefits of Andarine S-4

Andarine S-4 might be the most versatile SARM that was ever synthesized in a laboratory. It is the only SARM to have been given the green light for phase 2 clinical trial. After initial success, it was used to treat age-related muscle issues (muscle wastage), osteoporosis, and the results of hypogonadism.

Stage 1 examinations have proven that upto 3.3 pounds of muscle growth is possible within 3 months with minimal changes to your working out plan and nutrition. The liver is not harmed in the process and as an added benefit it also boosts male libido.
