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)

To whom

The preparation is intended for adults performing leisure, amateur and professional training in order to form their training capacity and effectiveness and maintain quality muscle mass.

Zinc contributes to the maintenance of normal testosterone levels in the blood. The scientific research prove that zinc is an inhibitor of prolactin, Vitamin B6 contributes to the regulation of hormonal activity.
