"The problem is that prescription testosterone doesn't just give your T level a boost: it may also increase your risk of heart attack. It can add huge numbers of red blood cells to your bloodstream and shrink your testes. In some men, it increases aggression and irritability. Children who accidentally come in contact with the hormone can develop unwanted pubic hair and genital changes. Last week, a large study published in the journal PLoS ONE found that, within three months, taking the hormone doubled the rate of heart attacks in men 65 and older, as well as in younger men who had heart disease."
-Okay increasing RBC is definitely a risk, but with careful monitor of blood work and blood donations this isn't a problem.
-Shrink your testes? Sure without HCG which most doctors don't prescribe unfortunately.
-Increasing aggression and irritability. In my experience with aas as well as viewing those on it, it basically accentuates who you are. If you're a hot head, you'll become more of a hot head. Personally I'm an angry douche with Low T but a sweat teddy bear with it.
-Children growing pubes and having their penis grow. This one doesn't really apply to us haha
-as far as doubling the rate of heart attack in men 65 and older, this is probably do to poor monitoring of blood work.
The article itself states the reason why all these are common symptoms.
"Too many doctors are now writing testosterone prescriptions without even measuring the patient's hormone levels, much less re-testing for confirmation and adjusting the dose after prescription. Up to a quarter of these prescriptions are dispensed without a blood test."
