here is an interesting counter to that since in this last psychology class I took I read about a study done with rats and AAS regarding how it effects the brain, chemicals and overall processes etc, aggression was some how tied into the mix. anyways it compared oral forms to injectables and used anadrols winstrol, masteron and nandrolone... neither oral had any effects on the brain, its chemicals, processes etc, but both injectables actually did, and believe it or not nandrolone was actual listed as having the greatest effects on the brain. Like I said aggression, drive, "alpha male" side was included in the mix. Granted I dont recall all of the specifics since I've learned that pretty much any aspect regarding AAS outside of the bodybuilding and sporting world realm tends to always put AAS in a bad light with some or all adverse effects.... The main thing I got from the study was that it actually showed how AAS can have an effect on the brain and nandrolone having the greatest effect...
