Dude, just stop, you're embarrassing yourself trying to defend the indefensible:
Roids would be very easy to find. If there’s medicine, there’s steroids= FALSE, most are made in underground labs nowadays and have very short expiration dates, so they would all be useless by the date the game is set in, also medicine IS necessary for the survival of society, an underground steroid lab is NOT.
hyperproteical/calorical diet= without steroids it would be impossible for her to get that build, with ANY kind of diet, period.
AND you forgot the most important part of muscle growth: sleep/rest, in such situation, long walks and cardio type efforts would surely end any gains...its a SJW feminist design no need to defend it...
