Prolactin inhibitor in a testosterone booster - is something completely new! Several years ago experts from Olimp Laboratories stopped designing dietary supplements aimed at increasing the internal production of testosterone affecting the body by using only one biochemical mechanism. As science develops and the demands of professional athletes concerning the quality of products continue to increase (it is now required that as well as increasing the level of testosterone, that products neutralise the adverse effects of elevated concentrations of oestrogen and prolactin), the whole potential currently offered by completely legal and safe active substances has been implemented in one advanced product stimulating the production of testosterone - the DAA Xtreme PROLACT-BLOCK. At the same time, it is also a viable alternative to extremely harmful anabolic-androgenic steroid-like products. Nowadays, virtually all sports based on strength or speed and strength workouts, directly connect workout results with the body’s level of testosterone. DAA Xtreme PROLACT-BLOCK 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 Xtreme PROLACT-BLOCK is perfect for you! The negative consequences of elevated prolactin levels can include, in particular, a reduction in testosterone levels in men(1), this is also as a result of reducing the secretion of gonadotropin hormones (LH, FSH) by reducing the level of GnRH(2). This may lead to erectile dysfunction as well as also permanent hypogonadism, not to mention an immediate reduction in testosterone level, libido, mood deterioration, fitness abilities and regeneration rate, and consequently training progress. The new composition concept of the innovative “T-booster”, created in the ultra-modern laboratories of Olympus Labs®, holistically encompasses the induction of the internal testosterone synthesis in the male body, assuming a minimum biosynthesis and/or the reduction of the negative impact of hormones, such as, among others, oestrogen and prolactin, on athletes, thereby setting new trends in the production of effective and physiologically optimised testosterone boosters in terms of the effectiveness of sports exercise. Olimp Sport Nutrition® has developed a new concept for the composition of T-boosters, which has been implemented in the DAA Xtreme PROLACT-BLOCK! How it works: functionally the DAA Xtreme PROLACT-BLOCK affects the body by the presence of D-aspartic acid (DAA), which naturally occurs in our endocrine cells, adrenal glands, pancreas, thyroid, parathyroid and largely in the pituitary gland and testes. The highest concentration of this amino acid was found in the venous blood plasma of the testes, parenchymatous cells, seminiferous tubules and testicular interstitial fluid(3). The participation of DAA in the mechanisms regulating testosterone production supporting the development of muscle mass has been described only in recent years. It was observed that D-aspartic acid releases GnRH from the hypothalamus, luteinising hormone (LH) and growth hormone (GH) from the pituitary gland, and testosterone from the testes(4). Studies in humans unquestionably confirm the effectiveness of pure DAA. But Olimp Sport Nutrition® offers something more… In 2009, studies were conducted(3), during which the impact of DAA (3.12 g/day) on the testosterone and LH levels in healthy men was analysed. The experiment lasted 12 days and clearly depicted the effectiveness of the analysed DAA. The level of testosterone increased by 43% and LH by 33%. Moreover, after ceasing supplementation with D-aspartic acid the persistence of elevated LH and testosterone levels was observed (see table below). In the placebo group, there were no significant changes. 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 BASELINES AFTER 6 DAYS OF USE AFTER 12 DAYS OF USE 3 DAYS AFTER CEASING SUPPLEMENTATION LH (mIU/ml of serum) Persons taking DAA 4,2 ± 0,5 4.5 ± 0,6 5.6 ± 0,9 4,8 ± 0,8 Persons taking placebo 4,2 ± 0,4 4,3 ± 0,7 4,2 ± 0,6 4,1 ± 0,5 TESTOSTERONE (ng/ml of serum) Persons taking DAA 4,5 ± 0,6 5,2 ± 0,7 6,4 ± 0,8 5,8 ± 0,6 Persons taking placebo 4,6 ± 0,5 4,5 ± 0,7 4,7 ± 0,7 4,6 ± 0,7 Such prominent effects were achieved with a DAA daily dose of 3.12 g. Olimp Sport Nutrition® went a step further by offering a daily dose of 3200 mg of pharmaceutical grade DAA to a group of the most demanding people striving to improve the quantity and quality of muscle mass as well as physical performance. With complete knowledge of all of the effects of the DAA dose, researchers from the Department of Research and Development of Olimp Sport Nutrition® decided to effectively limit the possible consequences of elevated secretion of undesirable prolactin. The simplicity as well as safety and ingeniousness of the solution lies in the fact that simple compounds, i.e. vitamin B6, vitamin E and zinc (5, 6, 7) were used as inhibitors of this hormone in the appropriate weight ratios closely oriented to people with increased internal testosterone production. In this way, the devastating effect of prolactin on muscle mass, endocrine balance, libido and exercise capacity has been reduced to a minimum, at the same time making the DAA Xtreme PROLACT-BLOCK an excellent product for people with a genetically determined sensitivity to prolactin, permanent problems with achieving lean, sculpted and muscular figure, often unaware of the factual causes of their failures in dietary and training endeavours. The fact that D-aspartic acid has a positive effect on fertility, improving sperm volume and motility(8), is not without significance in times of reduction of male fertility in general population becomes an issue of paramount health importance. DAA Xtreme PROLACT-BLOCK means ABSOLUTE SAFETY - you can cease the supplementation at any time without consequences, such as endocrine imbalance. DAA Xtreme PROLACT-BLOCK created by Olimp Sport Nutrition® gives you a unique opportunity to increase testosterone production, while reducing the potential negative consequences of the body’s sensitivity to hormonal cascade resulting from elevated androgen levels.
