Does fadogia agrestis increase your testosterone?
Do not use it. There is barely any human evidence that fadogia agrestis raises testosterone, it is not authorised for sale in the EU, and animal studies show damage to kidneys, liver and testes.
Fadogia agrestis is sold online as a natural testosterone booster, but good research in humans is almost entirely lacking. Its popularity comes mainly from animal studies and online influencers, not from clinical evidence.
It is also problematic legally and in terms of safety: in the EU fadogia is an unauthorised novel food and therefore may not be sold as a supplement.
And safety is a cause for concern: at higher or prolonged doses, animal studies show damage to the kidneys, liver and testes, precisely the organ it is supposed to help. In short: unproven, unauthorised and potentially harmful. Do not do it.
