Ok, I'll do a little on #2 since #5 is so long haha.
I think way too many kids or basic gym rats use gear. Like you said basically, why cycle to lose your gains afterwards and probably have low test? I can't tell you how popular (as you prob know) superdrol was especially for younger guys. Everybody who played high school sports was on this shit. Hell, I even heard that a high school coach in my area was handing it out to his players (talk about mother fucking irresponsible - I'd sue every possession that coach had if I could prevent myself from killing him first if I had a son on that team).
Say you are a natty dude with no real idea about gear and training/diet and you take superdrol for 4 weeks and put on 25lbs (and 50lbs on your bench - which is your favorite exercise bc you're 1} a douche and 2} American haha) cause it's your first cycle. Well then you take clomid for 4 weeks and cry yourself to sleep every night watching bambi bc estrogen is sky high and testosterone isn't even there. At the end of four weeks, you're feeling a little better and still up 15lbs and your bench is still 30lbs higher than it was so you're happy. Well, in my mind that is a failure. Here's why: 1) you can put 30lbs on your bench in 8 weeks naturally if you concentrate on it and program it correctly unless you are already very strong; 2) you felt like shit for 2 months straight - enough said; 3) you possibly damaged your endocrine system; 4) you are less healthy now than you were and 5) you endured mental stress for no reason.
Sure if you cycle 4 times a year you are better off being on than natural (in terms of size and strength), but I'd say you are cycling being off rather than cycling being on and you are really now yourself when "on."
In regards to the other part, TRT for oldish guys or previous gear (bc IMO Every man has the motherfucking right to have normal hormones regardless of how yours got fucked up) users is the shit and necessary in the estrogen infused skinny jean douche bag pussified world we live in today. I don't think any rational guy doesn't know the benefits of high end of the normal range test such as libido, muscle mass, energy, mental clarity, good aggression, reduced bf, IQ, ect, but a lot of people don't know that high test also has been correlated with: 1) reducing thoughts of one's mortality - a fucking pointless activity; 2) preventing obsession with material possessions (can be linked to low test), and 3) pre occupation with politics (also strangely linked to low test - I guess guys with high test would rather turn off CNN and fuck a girl and lift weights than hear about the world's bullshit).
