Die Hard supports the foundations of erection, helps increase sperm production and motility, and contributes to raising testosterone levels. The supplement was developed to support the natural processes occurring in the body. For the swelling of the penile corpora cavernosa, the so-called endothelium-derived relaxing factor is essential. For it to be produced, an adequate amount of nitric oxide is necessary. Nitric oxide is produced from L-arginine (with the involvement of free intracellular calcium) and is responsible for relaxing the corpora cavernosa, enabling erection. Age, unfavorable habits, and lifestyle can reduce arginine levels in the body. Die Hard contains a higher dose of arginine and calcium than competing products, kept just below the legal limit. This optimizes the formula for effectiveness.
