hey guys I am looking to gain muscle mass and loss some fat. That being said I spend at-least 2 hours at the gym every day and I feel like I am destroying my body (in a good way). Anyway I was browsing around GNC's website yesterday for a pre-workout and I found a product called GAT Nitraflex I was just wondering if anyone on here has heard of it / taken it. It says its a pre-workout with a T-booster and I'm thinking I need a little bit of a boost in the T area. All the reviews I found yesterday were split some people loved it and some hated it. So I would like to have your opinion.
