This is achieved by the patented MBX™ Muscle Boosting Matrix developed by Applied Biosciences, London. The matrix consists of precisely calibrated amounts of boron, zinc, D-vitamin and D-AA amino acid. Second testosterone boosting agent is Eurycomanone and several other active ingredients in Eurycoma Longifolia (also known as Tongkat Ali) plant, known as a potent testosterone booster in its own right (important – read the warning here).
One dose of Tetrasterone™ contains 1g of grape seed extract which has been clinically proven to have stronger anti-estrogenic effect than Tamoxifen, drug popular with bodybuilders. Eurycomanone has also clinically proven anti-estrogenic effects.
Eurycomanone has been clinically proven to counter the catabolic effects of catecholamines. Therefore Tetrasterone™ also prevents muscle breakdown.
Active ingredients in Tetrasterone™ prevent binding of testosterone molecules to SHBG (Sex Hormone-Binding Globulin), thereby greatly increasing the bioavailability of testosterone.
|Tetrasterone: Increases own testosterone
|Tetrasterone: No side effects (on the contrary, has many health benefits)
|Tetrasterone: Legal and containing no banned substances
|AS: Bringing external testosterone to the body (negative loop effect leads to inhibition of own testosterone production and impotence)
|AS: Dangerous side effects including heart failure, vascular damage, impotence, hair loss, skin problems
|AS: Illegal, athletes banned if tested positive
A significant part of naturally produced testosterone is turned into estrogen by enzyme aromatase in a process called aromatization. Since estrogen has effects that contradict those of testosterone it is in your interest to prevent this process.
Second reason to block estrogen production in men is that your body attempts to keep certain blood levels of steroid hormones. Both estrogen and testosterone are steroid hormones and if you block estrogen, the levels of testosterone go up to make up for the deficit (based on this rule bodybuilders using anabolic steroids use chemical anti-estrogens after the steroid cycle to re-start natural testosterone production, this is called PCT or Post-cycle therapy).
