As a personal trainer, working out is one of my favorite hobbies, so I’m always checking out stores like GNC for a good deal on protein shakes and other supplements. GNC isn’t the cheapest around, but they’ve got great products, and occasionally they’ll have a clearance sale that can’t be beaten. I’ve purchased whey protein, creatine, and various protein bars from GNC and I can’t complain. The staff here is also really knowledgeable about the purpose and effectiveness for all of the different supplements, so that really helps when I’m browsing. If you’re thinking about buying workout supplements, definitely check this place out!
