The reason no one has found a better way is because hypertrophy is because it’s well understood and there’s no “better” solution. mTOR is the primary hormone pathway.thy increase the adaptation ceiling by increasing RBC, reducing protein breakdown, etc. Thereby reducing rest needed, so mTOR is heavily unregulated.

This is one of the view places where “if we could we would” is the correct answer. There is so much money in the space of anabolic cheating, the clandestine scientists would’ve already developed it.
