This is the quality for which it is included in testosterone booster supplements and similar other supplements designed to treat sexual dysfunction and low libido. A study performed on male lab rats where four groups were given doses or placebo of 25, 50 or 100mg/kg body weight of bulbine extract. At the end of the 14 day study, the rats in the 50mg/kg body weight group had showed the highest androgenic and anabolic effects.
