Natural testosterone supplements, also known as testosterone boosters, contain potent herbal extracts that can prompt the body to produce more testosterone. Testosterone boosters also contain ingredients to block the conversion of testosterone into DHT and estrogen. Other ingredients help by unbinding testosterone that is bound, and therefore unavailable for use by the androgen receptors of muscle tissues.

Universal's Get Jacked Stack contains the natural testosterone-boosters tribulus terrestris, avena sativa, and an herb called longjack. In addition, it contains ingredients for blocking DHT (dihydrotestosterone), estrogen and cortisol.
Universal's Animal M-Stack formula is non-hormonal, which does not mean that it has no effect on testosterone. The ingredient safed musli may help to unbind bound testosterone. The potent adaptogens may also help with normalizing the body's hormonal environment.
