Testosterone Booster Supplement

The first testosterone booster inhibitor of prolactin! The most powerful testosterone booster!

  1. Significantly increased levels of testosterone
  2. Increase endurance during exercise
  3. Improves mood and concentration
  4. Increases levels of growth hormone in the body
  5. Increases the secretion of nitric oxide


D-Aspartic Acid (DAA) is the newest natural testosterone booster on the market. DAA is the D-form of the amino acid aspartic acid. The body can produce DAA from the nonessential amino acid L-aspartic acid (the dietary form of aspartic acid). D-form amino acids, such as DAA, are found in higher concentrations in specific tissues in the body. For example, higher concentrations of DAA are found in the testes, pituitary gland, and hypothalamus all of which are areas involved in hormone production.

A few years ago, ended the period when the dietary supplement designed to stimulate the production of testosterone inside the body affected only by a biochemical mechanism. Along with the growing demands of customers, as to the effectiveness of the product, expressed through its potency, gradually increasing the complexity of this type of supplement, which is now through its complex composition, must allow an action synergy of many active ingredients.

It should be noted that modern, advanced supplements to raise the level produced in the male body (endogenous) testosterone in the smallest details are trying to imitate the mechanism of action and the path of modern, proven and highly effective drug treatment, while providing a viable alternative to the extremely harmful measures ingredients.

Currently, virtually all sports-type force or speed-strength, especially those silhouetted directly connect the training result of high levels of testosterone in the body.

DAA is a panacea for excessive fatness during heavy mass cycles!

Unfortunately, a common disadvantage of products aimed at increasing the level of male androgen is the simultaneous raising of oestrogen levels (the increasing activity of the aromatase enzyme), which in turn stimulate the secretion of prolactin from the pituitary gland. Their effect can thus be compared to a double-edged sword, which, overall, brings more losses than gains, especially in people sensitive to prolactin or of its genetically determined increased production, further intensified by eating popular older type T-boosters.

If there is a risk that you belong to the group of people with a genetically determined high level of prolactin, DAA is perfect for you!

The negative consequences of elevated levels of prolactin can include in particular the reduction in testosterone levels in men (1), and also as a result of reducing the secretion of gonadotropin hormones (LH, FSH), by reducing the level of GnRH (2). This may not only lead to erectile dysfunction, but also permanent hypogonadism, not to mention an immediate reduction in the level of testosterone, libido, mood deterioration, functional capacity and speed recovery.

Aiming to improve the physiological effect typical for T-boosters from previous years, a new concept of the composition of those products in a holistic way that recognizes the increasing production of testosterone in the body of a man, with a minimum of biosynthesis and / or limiting the impact of hormones on undesirable activity profile for athletes, m .in. estrogen and prolactin, thereby setting new trends in the production of effective and physiologically optimized towards performance sports exercise testosterone boosters.


Human studies confirm the effectiveness of the undeniably pure

In 2009, the study was conducted (3), during which examines the impact of DAA (3.12 g / day) on LH and testosterone levels in healthy men. The experiment lasted 12 days and clearly depicted analyzed the effectiveness of DAA. Testosterone levels increased by 43% and 33% of LH. Moreover, after stopping supplementation with D-aspartic showed persistence of elevated levels of hormones - LH and testosterone (see Table below). In the placebo group, there were no while no significant changes.

Olimp Cutting Edge Supplements

Absolutely uncontrollably knowledge relating to the whole of the effects of the applied dose of DAA, in collaboration with scientists from the Department of Research and Development Olimp Laboratories decided to effectively limit the possible consequences of increased secretion of how prolactin undesirable. As the inhibitors used simple compounds, ie. vitamin B6, vitamin E and zinc ( 5,6,7 ) in the appropriate weight ratios closely targeted for persons with increased internal testosterone production.

In this way, the devastating effects of creatine on muscle, endocrine, libido and physical work capacity has been reduced to a minimum, making both of DAA an excellent product for people with a genetically determined sensitivity to prolactin, permanentnymi defatted problems with working out, carved and athletic and muscular body,often wearing a factual awareness of their causes failures in dietary and training procedures. Not without significance is the fact that D-aspartic acid has a positive effect on fertility, improving volume and sperm motility (8), which in the age of the population-wide reduction of male fertility takes care also of great importance.

With the DAA you get a unique opportunity to increase the production of testosterone, while reducing the potential negative consequences of the significantly increased level (higher concentration of prolactin). The effect is fully stable, and the cessation of use of the product does not result in endocrine disrupting effects.

DAA Xtreme PROLACT-BLOCK is a daily dose of DAA which is even greater than the dose which was proven to be effective in studies.
