Not sure man...sounds like he might be juicing

You know, there are natural ways to increase your testosterone levels.  Leafy vegetables and nuts increase it, and so does some exposure to sunlight.  Check out http://www.mistermanpower.net , its got a full guide on libido enhancement that I've been following, and my testosterone has gone up, and so has my s*x drive (added benefit).
