Its moreso the fact we're talking about illegal drugs, not 'power amps', and trying to say they help you 'get stronger' (which isnt something we should be promoting on the wiki).
A) Nam-Gyu is a moron, who didnt have them to begin with, and was under their effects. Just because he says he 'feels stronger' (because hes under the effect of them) doesnt mean it literally makes him stronger. If anything, it decreases the 'anxiety' and thus makes him feel sstronger, but its not Popeye and his spinach. Not a reliable source.
B) Squid Game is grounded. They arent trying to say that you get physically amped with drugs, no matter how much they give you a temporary morale boost. If anything, im still finding it difficult to believe people scale to 9-C
C) You were using ketamine as an example. but just because smthn would be 'stronger than ketamine' doesnt mean it has the same exact effects and more. This isnt something you can chainscale like that? You cant say whatever Thanos was taking can do everything ketamine can do and then some just because 'its stronger
Thats all
