Their knowledge comes from the same place ours comes, remember they started out not knowing anything the same way we did. Trial and error, research to an extent until they are able to get in with the right click and get the right coachs and trainers. It involves a lot of dedication, a lot of time, a lot of food and yes a lot of gear. Anyone who thinks Olympia stage contestants run 500mgs of test and 600mgs of tren and these doses will get you there are grossly mistaken. Although diet, rest and exercise are the staples of success whether your a pro or not you must acknowledge that supplementation is a major role in the process. When they say to be big you gotta go big does not just apply with weight training. I can honestly say that one of the IFBB pro's that I know would never be where he is today without spending an ungodly amount of money on gear and would not continue to be where he is with out the money and gear from his sponsors regardless of the godlike genetics he has.
People who look at the pros and think they would like to be where they are at usually tend to only see the good side of things, talk to one of them in a serious conversation or read up on the negative of being 5'8 300lbs in the off season. Or the amount of pain they endure on a daily basis to be in the shape they are in. Most people shudder at the thought of running 10iu of insulin, where in reality is a very small dose. Try running 10iu humalog before every meal and 60iu humilin R post workout along side 20 iu of gh per day. It will take it to a whole new level. I DO NOT RECOMMEND DOING THIS just stating one protocol that 1 guy I know uses with success but has been doing it for a very long time and worked his way to it. Plus he has doctors, trainer, coachs who follow him with everything he does, we do not have such luxuries
