Probably would have been useful to define addiction. Just because someone enjoys or uses something to assist in their goals and enhance their life doesn't make them an addict in my book. If we use a low enough level definition every person on the planet is an addict. I don't subscribe to "the government says xyz" to define addiction either... Not an anti government rant but with cigarettes and alcohol legal they can fuck off for this purpose.
For what it's worth I was off for many years and got on prescribed trt on a lark. Blood work showed I was a candidate and a lot of stuff like lipids was legit bad. 6 months later my bloods were 90% better (only change was trt) and even a heavy blast of the worst offenders doesn't nuke me close to where I was before. I blast moderately, try to be health conscious, and legitimately enjoy my cruise or trt off periods. I look better, feel better, think more clearly, have more energy, like to think I perform better at my work, and am certainly in better health (back by all kinds of data) than I was before. If that's addiction, I'm all for it. That said in no way other than legally, which is a real pisser, has it been a negative for my life, health, family or work. Good trade. I view it the same as I would the reasonable use of a supplement - except that it works.
