Testosterone is the primary male hormone responsible for many functions inside the body, including muscle gain and fat loss. Naturally promoting testosterone greatly improves the body’s ability to put on a higher ratio of muscle to fat since this is what testosterone signals the body to do. Testosterone can be supported through herbs such as DivanilTM and Icariin or synthetic Aromatase Inhibitors (AIs) such as 6-Bromodione, 6-OXO, and ATD.
Gaining muscle requires that catabolism (muscle wasting) be at a minimum so taking BCAAs and Coleus Forskohlii is important. Take BCAAs between meals and during training for maximum effect.
Arachidonic Acid is excellent for gaining lean muscle mass and minimizing fat gain on a bulk. It works through pathways influencing prostaglandin synthesis and has received excellent reviews.
