What is quack about it? Lots of people are noting anecdotally that is has huge benefits. Are there strong studies disproving this? As to the negative effects, what is the largest/longest term/most reputable citation you have for us?
What's quack about it is testosterone users calling themselves "doctors" to sell testosterone to other people. I haven't looked into research on either side so couldn't tell you whether I think it's a good or stupid thing to do, other than that if I did consider it I certainly wouldn't be considering the anecdotes of these people useful data.
It sounds like you are the one spouting quack science.
Sure all muscle gains are temporary. And TRT is typically used by people who would be at an age where baldness is common anyway.
Would you mind to elaborate about the side effects? The article sounds too good to be true.
The side effects of exogenous testosterone are far over blown, especially at a TRT level dosage (about 200 mg/week depending on the ester used). Many of the side effects can be managed by using medication such as Arimidex.
