yeah drug buffing is a strat in FO 3/NV for beating the General and the Leget of the east but i think he means he wants a way to be stronger without becoming permanently overpowered which is understandable.
Honestly if Indivi added a part to the sanctum to mess with stats it would solve that small problem, as anyone could use it to be over/under powered when they wanted to or just not touch it at all for the same experience.
