Glutamine is the best supplement. I used it in amy prtoein shake after work outs and it eliminates any muscle aches that I normally get the day after. It tastes like complete crap but its worth it.
Glutamine is actually minimally effective when taken orally. You need a lot to get an effect. That;s why GEAR contains no glutamine. Use $100 of GEAR a week and $100 of glutamine a week and you'll grow twice as much muscle on the GEAR.
