LOL, I have seen someone on test, deca and anadrol year round for two years and gain 10 lbs of muscle.
I have also seen a guy first time do juice and gain 25lb on 1 bottle of test. It is all about genetics and the way you respond to hormones,
Now put 100 random guys on as much juice as humanly possible 6+grams per week and a lot of gh 20-30iu per day and only 5 of those men will end up this guys same size and conditioning. And only one of those 5 will end up with the same caliber of shape to his muscles.
Now take 25% of the drugs out and you would get the same results with 1 out of a thousand, take another 25% off and would get the same results with 1 out of a million, but even Ronnie Coleman genetic would require one to mega dose to look like this..
Ya I know reality sucks right?
