A “Low Testosterone Gel” advertised for men, Turbo-T is advertised as a cure for moodiness, low energy and difficulty in maintaining erections. Directions for use advise that it should be applied to the body in much the same way (and much the same location) as an underarm deodorant on a daily basis, and presumably absorbed through the skin.
As it is mostly aimed at aging men living in Florida, the overwhelming possibility is that Turbo-T is actually more of a placebo than anything else.
