5 Reasons Why You Won't Tell Anyone About This Performance Enhancing Product
#1 Improve Workout or Race Time
Would you tell your training partner why you started beating them in workouts?
Why tell them you are on a clinically proven, certified drug free performance product that has over a dozen open label and published clinicals showing a double digit increase…when you out rep them?
#2 Increase VO2 Max
If you have a hard time catching your breath and you found something that makes you feel like you have a third lung... why would you share your advantage?
#3 Maintain Energy Levels
Feel worn out before, during, AND after workouts? Energy drinks not cutting it? BUT all of your friends seem like they aren't?
If all of a sudden you looked forward to the next workout and felt significantly better during it... would you tell your friends?
#4 Improve Recovery Time
If a product was clinically proven to reduce Creatine Kinase (CK) levels by 6x which means your muscles recover better during workouts and after... would you keep that to yourself and let your friends suffer?
#5 Less Muscle Soreness
If a product was clinically proven to reduce lactic acid buildup by double digits meaning you wouldn't be as sore the next day... wouldn't you keep that to yourself and let all of your friends be sore and miserable?
