The category of hormone boosters and stimulants includes dietary supplements based on tribulus, HMB, arginine, DAA, Maca, etc. For example, arginine increases the production of growth hormone, enhances the pump effect, and aids in better removal of lactic acid from the muscles, which is particularly beneficial during strenuous workouts, making it a common component of pre-workout formulas. The primary function of HMB is to improve muscle regeneration and increase the utilization of the proteins consumed for muscle building.
This category also includes products that are legal and safe substitutes for promoting the production of testosterone and growth hormones in our bodies, with a focus on the extract of the plant tribulus terrestris. These are by no means "anabolic hormones" or similar prohibited substances but revolutionary agents based on natural steroid saponins that enhance the growth of high-quality muscle mass.
