I go absolutely mental on creatine, and yet with other people (including my housemate) it has almost no perceived effect.
what am I lacking naturally that the creatine is making up for?
"mental": like I've drunk red bull - hyperactive, need less sleep. This persists for the first 1-2 weeks of taking after a short break. Also my strength endurance increases massively.
I guess to some extent the answer to the question doesn't actually matter - I just need to enjoy the result, but I'm curious nonetheless...
