This is a paid ad for a testosterone booster, which seems to be pretty widely displayed
The ad makes the following claim:
Studies from India and Queensland, Australia have shown strong and even spectacular results with the key ingredient in Nugenix, Testofen®. Benefits include increased drive, improved performance, and enhanced muscle mass. These benefits primarily come from safely boosting free testosterone levels.
Is this claim accurate?
I see the following parts to the claim:
There were studies done on effects of Testofen (Fenugreek plant product)
Benefits include increased drive, improved performance, and enhanced muscle mass (I'm unclear what "improved performance" means)
There's a causative effect for the changes from free testosterone boost.
The boost is safe.
