There’s a good reason more stallions than fillies win horse races: Stallions have bigger muscles and more of the muscle-powering hormone testosterone than fillies do. Knowing that, most racehorse trainers would feed prohormone products to the stallions they train for the track if only they could!

Prohormones are hormone precursors that liver enzymes convert to anabolic hormones in the body. Though earlier versions of prohormone products were banned from the marketplace, luckily for human athletes who want to increase their muscle size, strength, and endurance, a new version called 1-Androsterone is available.

Manufactured by Advanced Muscle Science, a company with more than 20 years of experience in producing cutting-edge bodybuilding supplements and ergogenic aids for the sports-nutrition industry, 1-Androsterone offers many of the same beneficial effects that 1-androstendiol and 1-test did—and because the formulation is 100 percent legal, you can take it knowing your body is protected from dangerous substances. Unlike virtually every “methyl” prohormone on the market, 1-Androsterone is completely nontoxic, an orally active compound that occurs naturally in the human body. Moreover, in addition to being exceedingly powerful, it’s also completely non-aromatizable to estrogen.

Both men and women need a certain level of naturally occurring steroids in the body to build muscles and increase bulk. This is even more important for people over the age of 25, since natural levels of testosterone in males and progesterone in females begin to decline after this age.

While some formulas claim to encourage healthy muscle growth and a steady supply of the essential hormone, many fail to produce results.

Used as a prohormone to testosterone, 4-androstenediol (4-AD) is designed to increase the natural production of testosterone throughout tissues in the body, making it easier to build muscle naturally. The 4-AD combination is used in many prohormone blends, but Advanced Muscle Science 4-AD is made with a proprietary blend and can be used both as a pre-workout stimulant and for its testosterone-enhancing effects.

Hormone regulation is an important element of muscle building and repair, and a variety of dietary supplements and formulas can enhance the body’s natural cycle of hormone production. Advanced Muscle Science has developed an anti-estrogen complex, Arom-X, to promote muscle growth and increase testosterone levels. As it reduces estrogen levels, Arom-X simultaneously increases testosterone production, supporting healthy sexual function and enhancing focus.

Estrogen Inhibitors: Who Needs ‘Em?
Having too much estrogen often leads to limited muscle growth and an inability to bulk up easily. Bodybuilders and other athletes have long sought to increase their testosterone levels to allow their muscles to grow in a relatively short time. A variety of steroid supplements promise to deliver noticeable results. New formulas have been developed in the wake of the Food and Drug Administration’s ban on prohormones in the United States, but legal hormone products such as estrogen inhibitors are still available for many bodybuilders, athletes, and fitness enthusiasts.
