This obviously leads to very unrealistic expectations for those that are natural.
The nattyorjuice subreddit is sobering material.
You can also go to a Testosterone replacement clinic and get an actual TRT prescription provided your T is actually low. If they are ethical, they will monitor to keep it within a healthy range so you don't go past an upper limit.
Your results will suck ass if you have low T.
Basically you have the male pattern baldness gene stay away from roids. If you need more motivation, study after study show women are less attracted to bodybuilder physiques anyway.
But, yeah, the non-initiated get a pretty skewed picture about how muscular one can get, naturally. That's a whole another discussion about body perception/dismorphia and societal idealizations.
It is also fairly easy to give an accurate estimation (esp. if fat percentage <10%) via FFMI.[0]
In some natural bodybuilding competitions anyone with FFMI >25 is ruled out automatically because of the high probability of steroid use at that point. Of course a non-trivial amount of natural genetic freaks certainly exist beyond this number and a case can be made that's the whole point of competitive sports: "freaks" competing against each other.
But then again once you are in the highly competitive game it is (nearly) impossible to resist PEDs.
I guess for that reason many different classes/federations exist to choose from.
There's near zero enforcement for steroids, so yes it does end up as an open secret.
The needs and goals of these two groups of people are going to be so drastically different that a lot of the advice is going to end up being counterproductive.
