Testo Tech by Watt is a food supplement based on D-aspartic acid, Maca, zinc, magnesium, arginine which promotes testosterone production. Testo Tech is a supplement that aims to encourage the increase of endogenous testosterone production. The main actor of Testo Tech is Acid-D-Aspartic acid. It is an endogenous and non-essential amino acid, therefore already produced and naturally present in our body. We find it mainly at the level of the nervous and endocrine systems. The choice to include it in Testo Tech lies in the fact that this amino acid, very present in the pituitary gland and in the testes, has a fundamental role in regulating the release and synthesis of the hormone LH (luteinizing hormone) and testosterone. Another amino acid involved in hormonal production is L-Arginine. In fact, it supports the action of GH, stimulates the release of insulin and is also fundamental for two other actions: detoxification from the amonia accumulated in the body and the production of Nitric Oxide, a vasodilator. To support the amino acids present in Testo Tech, the root of a Peruvian plant was selected: the Maca (Lepidium meyenii Walp), which grows spontaneously only at altitudes above 3500 m. In Peru it is well known for its nutritional properties and for the improvement it gives to mental and physical faculties; some studies show an aphrodisiac effect. Zinc is an element capable of supporting the action of testosterone and insulin (as well as having an antioxidant and supportive action for the immune system). Some studies have shown a close correlation between blood zinc levels and testosterone levels. The anabolic action of testosterone would depend on a good availability of zinc and another mineral, magnesium. In fact, it too is a mineral with positive influences on the production of anabolic hormones. To support all the elements, Vitamins B5 and B6 complete the action. We recommend taking it with a glass of water.
