I find it interesting that most of my friends/social set will (rightly) dismiss "high school health class" fearmongering over drugs, but when that drug is anabolic steroids suddenly every warning is true.
It seems reasonable to me that the same skepticism applied to claims about any drug's danger - claims which frankly derive from government sources interested primarily in social engineering - should also be applied to steroids.
My understanding is that many of them don't do bloodwork to test existing hormone levels and many that do use very liberal interpretations of what standard levels in men should be at a given age, etc.
Think of the "pill mills" that lead to the opiod crisis where as long as you had the cash someone would write a prescription. Note that I'm not insinuating similar levels of risk or harm, merely pointing out the flexibility of medical ethics for some doctors in these areas.
Use your favorite search engine and search "anti-aging clinic". They're in many US cities, available online, and a popular medical tourism destination.
EDIT: I also suspect these kinds of medical "interventions" are prevalent in Hollywood and elsewhere. For example, Hugh Jackman in Wolverine. This guy was born in 1968, which puts him at ~44 years old during filming. Look at his physique as a 44 year old man and tell me that was just from broccoli and chicken (especially considering his physique in roles leading up to Wolverine).
I'm not saying it's impossible, I'm just saying that the chances that so many of these mid to late 40s Hollywood actors have a physique that would be excellent on a 20-25 year old isn't likely due to just freak genetics, diet, and hard work at the gym. Especially when the budgets of these films can easily exceed $100 million.
Another factor is that there is relentless competition from a huge number of people trying to become a famous star: severe filtering that will select for intensely driven people (amongst other attributes that would drive someone towards interventions).
Indeed, we should.
I don't use androgenic steroids, but I'm right on the cliff where natural levels start falling off, and once I'm over it, I will give it some serious consideration.
trenbolone and other 19-nor substances are neurotoxic and thrash your internal organs.
fatburners like clenbuterol or dnp are uh, not good.
insulin (which is massively anabolic, btw) can kill you very easily if you mis-time your meals.
growth hormone enlarges organs at supraphysiological doses
I probably know more than that and haven't paid that much attention to hormones per se, so I imagine if this interests you, you could figure out a whole lot more from readily available information on the internet.
Steroids are not necessarily always bad, tho taking your body to the extremes of competitive bodybuilding probably is.
