250-750mgs over time will get you as big as you are going to get, you are just chucking money away if you believe short bursts of multiple grams is going to do any better.
Its your genetic response to the compounds that makes you a champion, not the dosage.
but long burst, there is a sizelimit you can go to withv 750mgs but the you plateu, to get bigger you have to take in more drugs.thats what happened to friend lf mine that had been on 1gram cykles and looked the same as 10 yeaes before and he complained it to me, i tod him to up the dose and he did and is alot bigger with the same diet now
