Personally, waste of time. it's a mag-10sales pitch. Article does not in factor in genetics, possible gear your on etc. I just train hard as hell and add additional glutamine an lucein to my BCCA's to my post work out protein shake. I'm 52 and shredded. I pound down a ton of food, mostly ultra-clean boring carp, but I never have to go through the bulk/cut B.S. that gym rats do. I'm just running a 200mg trt per week , good supps and train like hell. Not rocket science, hard work =good results.
