Be very careful about where you get your "cold hard facts" research about what does, and doesn't work in the world of size/strength training. Much research is very poorly conducted. Much is slanted towards achieving the researchers pet theories, and did I mention much is VERY POORLY conducted?
Some use animals. And while our metabolisms are remarkably close to many other mammals, that is often where the similarities end and what proves true in a mouse may mean NOTHING in a man. A big factor in human studies is who the humans are that are being studied. In America we very often use college students with little or no previous training experience. Shit ANYTHING works well at that point. On the other end of the spectrum are those studies using elite level athletes. WOW! How many reading this are Olympic level, or elite caliber athletes with the best genetics supported USUALLY by performance enhancing drug use? Do these studies tell Joe average training clean what is likely to happen in his or her body? Or even Joe average doing gear? Not likely.
I like studies and read a lot of them. If you are able to read discriminately and understand that what is true in the lab may or may not hold true in the real world with real people they can be of value. But if you get hung-up on their worth and hold dogmatic views because the "study says", well you are backing your self against the wall of unreason.
