As my doctor exlained to me, injections or gels or pellets are merely delivery systems for testosterone. If he is willing to give/ prescribe you gel, then insist on injections. If not, find another doctor. Besides, cost is the BEST reason for not doing gels; at least until a generic is available.
TRT is the wave of the future for all men which we will ALL want to try at some point in time or age. Go forth and grow!!
