Finally, the life of a steroid-user is not as glamorous as it seems. Steroids are expensive and illegal. They can do jail time if caught, and there are a lot of ancillary drugs and supplements that must also be taken to minimize the damage to their organs or to keep certain hormones in normal ranges (ex: Nolvadex). Their bloodwork (hematocrit, cholesterol profile, etc.) and blood pressure is often atrocious. They battle with sleep apnea and fluctuating moods and sex-drives, and many have trouble performing simple daily task such as wiping their butts or washing their backs. Last, their caloric intake is much higher (and expensive), and it becomes a chore to meet calorie and protein requirements day in and day out. The grass is not always greener on the other side.
I don’t believe that the body can grow strong due to tendon/CNS adaptations as you keep asserting. That may work for a few weeks when you begin a new exercise & improve motor skills and structurally adapt, but it will not last long. You will never get strong in the long run if your muscles are not also growing. But I think many people have vastly overestimated the impact on your appearance that gaining muscle actually has. Gaining 5 lbs of fat will make you appear much sloppier, but gaining 5 lbs of lean muscle will not make that much visual difference while wearing clothes
