Actually BB was exactly what was in the minds of scientists at the time...
Anrogenic anbolic steroids were first developed for and used in Eastern Europe for the purpose of increasing aggression in Nazi soldiers, building strength and muscle of elite-level athletics in the 1950’s, and the very specific use of building muscle and strength for weightlifting. Steroids became even more commonly used for bodybuilding purposes in the 1960s (Arnold and the "Pumping Iron" bodybuilding era, and US and Eastern European track and field athletes).
In the 1970s and 80s, scientists realized that beyond just being of use for enhancing athletic performance, simply by being anabolic they possessed many desirable physiological properties including the ability to increase protein synthesis, muscle mass, strength, appetite, and bone growth which made then useful for people with numerous wasting diseases such as Cancer, HIV, AIDS, burns, accidents etc.
However, of those steroids I have listed in my earlier message I would estimate 95%+ if not more are manufactured for the primary purpose of bodybuilding.
Does that answer your questions?
