Muscletech now has some new product called PUMPTECH. It claims it; induce rapid muscle growth, improve strength, boost vascular resonce, and increse nitric oxide production throughout the day.
i wonder about this company. everyone on here says the company is very reliable and reputable, but no one buys the stuff here or ever boasts about using it. also they have a new mass formula i was thinking of trying out. let me know if you guys try any of them.
