Re: does testosterone shots for males have any side effects
If he is low in testosteron before the injections start, he may gain muscle, lose fat, grow more body hair, have more sex desire, not be depressed as some examples of effects.
If too high testosterone it can convert into Estradiol E2. This can cause boob growth, fat gain, muscle loss, depression as some effects.
HRT is a balancing act to get the correct Testosterone:Estrogen ratio.
My ratio is best when it is over 30:1
Good luck, it is worth the effort if the balance/ratio is correct.
