Anyone who trains in high intensity sports, including weight training, and in particular body builders, powerlifters, cross fitters and combat sports athletes, know that Testosterone is the key hormone in mediating androgen processes such as muscle growth, weight loss, increased strength and some cognitive-psychological aspects. In addition, if you train hard and do not fully recover, you quickly enter a vortex of stress that will result in "cannibalising your muscles" and worsening your training performance, as well as the potential risk of getting injured, being subject to illness and significantly reducing the endocrine production of the precious male hormone.

The list of supplements marketed as "test boosters", i.e. with the power of stimulating this hormone, is extremely impressive and it is actually a "critical" factor for companies producing supplements as the financial stakes are very high. Testo-boosters are continuously being unveiled, described as "aggressive" and "fascinating", terms that serve to remind us of well-known doping drugs, with "catchy" claims, formulas with root extract mixtures sometimes well-known (more often less..) and all accompanied by amazing reviews. These are often mere smoke screens for athletes, victims of false misleading marketing and with many companies providing scarce real information.

The market for these products and its turnover is clear, they are always in vogue. But do they really work? Do they all work? Are we sure about what we are buying? Are they really backed up by science? My long experience in the field tells me, however, that sooner or later science appears on the scene with its answers and tests in the field, taking for example the "illusory" theories of many of these products, which have often been in the eye of the storm of the law, due to their suspicious and / or illicit "contaminating elements". A striking example is the issue of Tribulus Terrestris, which, for years, has been included in all these types of supplements as the most effective testosterone supplement ever with guaranteed and amazing effects. Everyone was fascinated by this herb with potentially stimulating qualities and, up to a certain point, the scientific confusion left room for a certain amount of doubt and... mysticism, thus providing a curious alternative to all males eager to be become an ever greater alpha male both inside and outside the gym...But what is the real story? Given that we are dealing with a very sensitive field, where there are many economic interests in play, it is good to be clear and the only way to understand the reality is to rely on science, which for years now has been studying the effects of a large number of natural substances that may have implications for testosterone stimulation. We are very often dealing with blends of "exotic" herbs, presumed to have "strongly" stimulating properties but which have very little or no effect on those who take them, or whose claims are revealed to be invalid by careful scientific studies. Some substances have a real positive influence (according to studies and analysis), others are of little significance for body builders, for example, and with others... many others you are simply "throwing your money away". This is exactly what happened with Tribulus Terrestris, the phytoextract that has been used for centuries in India to increase male and female fertility, to such as extent that it immediately attracted the attention of Western science.

Some studies have found that the main active ingredient of Tribulus, protodioscina (a steroidal saponina), has an effect on androgen levels , making it of interest to many companies. In fact, this led to the launch of many Tribulus Terrestris supplements. However, research has gone ahead and the first studies on human beings have begun to come out, including specific studies on men in training, or on athletes who practice sports such as rugby, and at the end of these studies it was not possible to notice any difference in testosterone or physical strength between those who took Tribulus and those who did not. After a series of in-depth studies relating to effective, noticeable and actual stimulation (and not minimal or temporary, far from the misleading claims often used), the scientific community has confirmed that Tribulus Terrestris has no effect in humans on lutein ( LH) or on the production of Testosterone or any other androgenic hormones, in such a way as to have the "promised" results, i.e. noticeable effects on physical strength and fat percentage. As always, the research and development department of Yamamoto Nutrition is always at the forefront and attentive to the world of research, thus, taking note of every update, we work to produce the best products, with raw materials of absolute certified quality, as is the case for TestoROL, structured with elements proven by science to support a real beneficial influence on the maintenance of physiological testosterone and support endocrine health in cases of intense training. No "miraculous herb", no element of "dubious" provenance or the result of witchcraft has been added; only elements that really support the physiological hormonal activity.

Long time supporters of this magnificent Ayurvedic phytotherapic element, we have included Ashwagandha as a key element, in the typology of the KSM-66 patent, the most studied and accredited patent. Traditionally in Eastern medicine it has been used to improve aspects of male health, so much so that the ashwagandha translates into "horse odour", referring to the fact that ingesting the herb confers the strength and virility of a stallion. Traditional beliefs aside, among its many actions as a powerful adaptogen and mental tonic, it has been shown in clinical human research that ashwagandha can have a positive interaction with testosterone and male fertility. Being an adaptogenic herb, it is very effective in reducing the physical and chemical effects of stress, where studies have shown that using an ashwagandha supplement significantly reduces the levels of cortisol, a factor that has an "antagonist" action towards testosterone, especially at the metabolic level.

It has also been shown that Ashwagandha supplements can be effective in stimulating testosterone production, an option to be taken into consideration in infertile men. Interestingly, another study noted significantly greater increases in muscle size following weight training, with significant increases in testosterone levels and muscle recovery compared to the placebo group, thus confirming a further direct and indirect specific property of this medicinal herb.
The new Testorol contains aspartic D-acid, an amino acid that is formed mainly in the hypophysis, in the hypothalamus and in the testes, which stimulates the production of signal molecules, which in turn enhance the testicle "messenger" activity with hypophysis. This is an amino acid that stimulates the body to convert cholesterol into testosterone. Aspartic D-acid is primarily a neurotransmitter, concentrated mainly in the pituitary (the main endocrine gland) and in the pineal gland (responsible for the production of melatonin, the sleep hormone) and is also found in the Leydig cells , or in those cells located in the testicles that have the specific function of producing Testosterone and other very important male hormones. It is believed that aspartate performs a function similar to that of a messenger: it receives signals from the pituitary gland and delivers them directly to the Leydig cell, which then begins to do its job by converting cholesterol into testosterone, so as a result, D-aspartic acid should favour an increase in testosterone production, enhancing the reception and transmission of messages between cells and testicles and vice versa. That's not all, however, high levels of L-aspartic acid in the brain cause the hypothalamus to stimulate the secretion of a significantly high number of gonadotropin-releasing hormones (GnRH), prolactin-releasing hormones (PRFs) and growth-hormone releasing hormones (GHRH). There are several significant studies demonstrating its favourable impact on hormone levels and fertility in the animals and especially humans, where it has been shown that D-aspartic acid, taken for 90 days consecutively, increases testosterone levels by 30-60% in men with fertility problems, as well as significantly affecting the parameters of seminal fluid quality and it has now become an element widely found in many specific male supplements.

TestoROL contains fenugreek, another phytotherapeutic element in which interest has been renewed after often discordant results, thanks to its fenuside content, a saponin that has a positive effect on endogenous production that, like testosterone, binds to the same testosterone receptors, when there is a fenuside concentration of around 50%. Fenuside is able to increase testosterone levels and has a testosterone-like action, binding to the receptors and mimicking its effects.

Ginseng Panax, probably the best-known adaptogen in the world, is often consumed by men for its sexual benefits. Although there are many uses of this powerful root for both sexes, the aphrodisiac quality of Korean Ginseng (Panax ginseng) has been attributed above all to males in traditional Chinese medicine. It is a precious thousand-year old root that increases the reaction capacity of the brain and adrenal glands, thus improving the body's resistance to the most diverse "stressing" agents of various kinds to which the organism is subjected. It is a powerful tonic that acts on all systems thanks to its ability to reinvigorate and strengthen all systems and organs. Korean ginseng can be useful for people recovering from diseases and traumas of various kinds. Moreover, it is very well known by athletes for its tonic and ergogenic properties that enhance performance and resistance to fatigue. In addition to its well-known aphrodisiac qualities, its beneficial effect has been observed in keeping testosterone levels balanced in animal experiments, especially after periods of testosterone suppression due to hypogonadism and / or infertility. It has also been noted in human studies that Korean Ginseng can help improve the symptoms of the complex sphere of male infertility (sperm motility, quantity and quality have been observed to increase during the analysis period, as well as an increase in the synthesis of testicular proteins), all this because Ginseng acts both at the pituitary axis and at the hormonal and neuronal level. Moreover, during severe exertion conditions, such as intense training, Ginseng acts on the hypothalamic-pituitary-adrenal axis complex and thus balances the release of hormones connected to the regulation of stress, so it favours a reduction in cortisol levels.

To ensure correct physiological support for organism endocrine production, Magnesium should not be forgotten. This mineral is known for having various functions that are important for the body, such as that it performs at the muscular level and with regard to physical performance ; we should always keep in mind that magnesium deficiency is associated with an increase in oxygen demand to complete sub-maximal exercise and reduced resistance performance. At the physiological level, nutrients such as magnesium and zinc are important because they interact with "anabolic" hormones and support them, see in particular with testosterone and insulin-like growth factor (IGF-1). More recently, more and more has been said about an interesting implication between magnesium and testosterone that has been studied in greater depth in studies on humans demonstrating that subjects who had received magnesium supplements could avail of higher levels of testosterone. Another point of interest for athletes, it has also been observed that magnesium and testosterone levels are low where there is inflammation and when ROS increases. An athlete who does a lot of physical activity also has a decidedly higher Zinc requirement, and it is often necessary to supplement it, given that zinc is involved in a large number of enzymatic processes with an important role in growth and development, neurological function, immune response and growth. These include enzymes involved in the synthesis of DNA and RNA, enzymes that regulate growth and development processes, enzymes that regulate immune function and enzymes involved in digestive and metabolic functions. As mentioned before, adequate zinc reserves are positively associated with serum testosterone, and several studies have shown that a zinc deficiency can even lead to a reduction in the synthesis of this hormone. Studies in humans have shown that zinc supplements can increase serum hormone levels in subjects with low starting concentrations (whereas in normal subjects no similar improvements are observed) , as may be the case in athletes subjected to intense training . However, administering zinc preserves testosterone levels after intense physical activity, a level that could otherwise be reduced and become a deficit.

Boron is an undervalued and for the most unknown element in calcium metabolism and the entire hormonal balance. Boron is an essential trace element for bone and joint health, whose main function is to ensure that calcium is well absorbed by the body. Boron's effects on the regulation of all steroid hormones including vitamin D and sex hormones by modulating them and re-balancing even the low testosterone levels in men in andropause should not be underestimated.

TestoROL® is a supplement that makes use of the best science has to offer and can demonstrate in the field, without creating false illusions or "illusory" claims. It enhances the response to psycho-physical stress thanks to the support it provides in the shape of plant extracts and proven active elements. It enhances the state of well-being of the hormonal axis of athletes who undergo intense stress and thus run the risk of adverse effects.

Si assumono tutte e tre insieme o è meglio suddividerle durante la giornata?

Un prodotto onesto. Ho provato con una confezione e sto continuando a testare alternandolo ciclizzandolo a anabolic Boost. Ho provato testorol e lo trovo interessante. Premesso non mi ha fatto acquistare kili di muscoli, ma ha supportato i miei duri allenamenti aiutandomi con la mia dieta a mantenere i livelli normali di testosterone che durante le sessioni anaerobiche vanno giù a picco. A me personalmente ha dato benefici sia nella sfera sessuale che nella sensazione in generale di benessere ed energia, cosa non da poco per chi ha dei regimi di allenamento intensi e fa fatica a recuperare le forze. Quindi un prodotto il quale non fa i miracoli nel mettere montagne di muscoli ma che invece funziona efficacemente come supporto all'equilibrio e il mantenimento di buoni livelli di testosterone nel sangue. Bravi.
