testosterone booster

Contrary to popular belief, none of the products declared as testoboosters actually contain artificial or natural testosterone. Many of their herbal ingredients contain saponins. These substances are also known by the name steroid alkaloids. They serve the plant as protection, among other things against fungi. The D-aspartic acid, however, is an amino acid. However, neither is a biological precursor of testosterone. Rather, the body's own hormone production is to be stimulated by these substances, so that our body significantly increases its testosterone production and so an improvement of the muscle structure is to be made - so the theory. Does that really work that way? Indeed, some of the herbal active ingredients have been shown to influence testosterone levels. However, these were often animal experiments or so-called in vitro experiments (experiments in a test tube). Experiments on humans under controlled conditions were mostly negative, as there were no effects on the testosterone balance in healthy men. And if they did, they were so small that they made no difference in muscle building. All proven effects, such as an increase in sperm count, a mild effect on testosterone levels, or an effect on libido (lust for sex) are limited to men with low sperm counts or men with erectile dysfunction. D-aspartic acid gives a similar picture, although the effect on the testosterone level is slightly higher for a limited time, but only people with sperm production problems have significant effects here. There was no significant effect in building muscle mass here.
