are you talking actual steron, the stuff used to stop women from having periods?
Anyway, what do you mean when you say neural pathways? I've never heard that term used in the gym industry. I think I get where you're going but I want to make sure.
1) Sterons is gym/internet slang for steroids. (Should always have an s/ be used in the plural form.)
2) Strength is not just a matter of having bigger muscles. Gaining muscle can certainly make you stronger, but you can also condition your nervous system to more effectively recruit the muscle you already have. The Bulgarian Method does this; you can add hundreds of pounds to your total without gaining any weight.
Neural pathways connect one part of the CNS to another. Newb lifters are notoriously bad at recruiting their muscle fibers. This is why a lot of newbs can't lift shyt for weight, even if they're big themselves: you actually have to practice recruiting those muscle fibers on command.
