Just from personal experience: Stay away from GNC and Muscle Tech products. GNC is over priced and the people that work there are driven by commisions they get from sales and will mislead you. As for Muscle Tech, I think they are overpriced even outside of GNC and are a lot of hype. Seems like they spend more money on advertising then they do on researching their supps.
