Prendre du Fadogia Agrestis pour stimuler la production endogène de testostérone.

what it claims

Consume Fadogia Agrestis (425 mg per day) to stimulate testosterone production, using cycling (for example, 8 weeks of use followed by 2 weeks off) to prevent risks of toxicity.

overstated

The idea that Fadogia Agrestis stimulates testosterone is based on an experimental study in rodents (Yakubu et al., 2005) that observed a significant increase in this hormone.

noli's read

The idea that Fadogia Agrestis stimulates testosterone is based on an experimental study in rodents (Yakubu et al., 2005) that observed a significant increase in this hormone. However, there are currently no clinical studies in humans to confirm these effects on our own vitality. The specific dosage of 425 mg per day is therefore a theoretical extrapolation that is not supported by any direct evidence in humans. Regarding safety, animal research (notably Yakubu et al., 2008) indicates risks of damage to the liver, kidneys, and reproductive functions during prolonged use or at high doses. The recommendation to 'cycle' intake to limit these risks is a common-sense strategy, but it has not been scientifically validated in humans. Thus, while the potential of this plant for our hormonal balance is promising in animals, the efficacy and safety of this protocol remain largely unproven in humans.
