Who should take care

Fadogia's safety in people hasn't been studied, so don't take more than the label says. Talk to your doctor first if you're trying to conceive, have a liver or kidney condition, or have prostate or hormone-related problems. Stop and see a doctor if you notice testicular pain or swelling.

Talk to your doctor or pharmacist before starting a supplement if you take any medicine, are pregnant or breastfeeding, or have a health condition.
