I'm not interested, way too many side effects. Lots of serious potential health side effects like enlarged heart, organ issues, not to mention more cosmetic ones like potential hair loss, skin problems . Typically chronic steroid users look older than their age, and many die early, of course depends on the dose and types of drugs but yeah. And the fact that if you get on you might just have to stay on because some people lose the ability to naturally produce testosterone properly if they stay on for a while. And if you get off you have to do post cycle therapy and there could be weeks/month of basically hangover as your t-levels drop way down and you'l probably lose lots of the mass you put on while cycling which propably wouldn't feel very nice.
Also is expensive, and illegal in my country. Overall its a no thanks for me. I'm 35 and pretty happy with my physique, I've never been massive but decently muscled and low bodyfat with good proportions, look better physique wise than 99% of the population at my age anyway. I'm not gonna turn into a bodybuilder or become an influencer who makes money off doing steroids and looking as good as I can so I don't see the benefit compared to the downsides.
Now when I get to my late 40's maybe i'll look into low dose trt because it seems kinda appealing but even that seems to have various potential side effects (mostly related to cardiac health) and they might shorten your lifespan. But might give you a bit more quality as you age, maybe. I'd have to seriously research it first at least, not something do be done lightly.
But before doing any of that i'd try to maximize natural avenues of being healthy.
Also the children issue you brought up. If you wanna do it i'd at least have a hard think about why you are doing it and if its really worth it when you have a family cause the side effects can be proper. Can affect your mental health and stability as well which wouldn't be ideal for raising kids i'd imagine.
But then again I don't know many irl steroid users, only a few ppl who took a few cycles of basic test. So my opinion is just based on years of consuming fitness content and hearing/reading about peoples experiences online.
As some popular guru, possibly Christian Thibaudeau said, you're basically renting a physique. You'll only look as good as you do whilst you're on, and look nowhere near as good when you're off (look at ex-bodybuilders as a reference), hence why many cruise on it to maintain the look all year round.
Hairloss has always put me off, although I've considered TRT once I get older (also 35).
