Christopher Walker

Neuroscientist | Author of Testosterone I/O | NoGym

The first student to get through Duke University's neuroscience program in 3 years, Christopher applied his natural interest in health and fitness to his education, and in around 18 months, naturally increased his testosterone levels above the medical range, overcoming the crippling effects of a pituitary tumor.

He created the Testosterone I/O program so you can learn exactly how to naturally raise your testosterone too. Because gels and pharmaceuticals are not a solution to the problem, they are just bandaids.

Learn how the system works, then manipulate it.

Christopher also blogs full time about health and fitness at NoGym and is the co-host on the Top-10 Health Show in iTunes, The Road To Ripped podcast.
