"Low" volume - higher volume over the bare minimum rarely tranlates to more growth. This is no argument, it would need to be elaborated, just a short statement of MY experience.
"Higher" frequency rarely translates to more growth either i.e bodypart specializing i.e. bringing up weaker bodyparts by doing more volume and/or higher frequency rarely works to satisfaction.
The "Dorian" program is almost as good as it gets from a hypertrophy standpoint. But then many claim Dorian, and even Mentzer etc, did just as much volume as "everyone else" so wtf Lol.
Strength is nice. Strength is correlated to muscle size. But that doesn't mean you will necessarily grow more by focusing on strength. Genes dictate most things. Strength obsession translates or correlates to more injuries in cases. I trained for strength. Still train for strength because I had low potential for size, no matter what. If I lived again I would have focused way more on drugs and letting them "do the work." Escalate dosages in a reasonable time frame and you get to your potential as dosages increase. Then it stops, fairly quickly if using all current drug avenues (e.g AAS, GH and insulin mainly at this point in time. Drug use and its potential for inducing gains mostly peaked in the mid 90s in my opinion, when everyone across the board increased the test dosages in particular) You are as big as your doses until you reach your potential which sometimes occurs very quickly.
