Not true. Moderate use of testosterone is safe with minimal side effects. Do a google search on "HRT" to see why many middle aged men are prescribed test by their doctors. The steroid users at the gym are taking 10-30x the normal amount of testosterone your body produces while HRT users are only taking about 2-3x normal. The main problem I see with this treatment is that the men would only get 1 injection per month and even with longer lasting testosterone, their levels are still going to vary wildly. What's the point of birth control if your libido crashes every 4 weeks.
