I wanted to drop you a thank for the help you gave me in figuring out my new supplement stack. Its working great and I have yet to hit a platque. I never heard of Jacked Factory but my stack with their products is kicking hard every workout. Can't thank you enough and I will always come here first when looking for advice and ordering my gear.

I just wanted to say how impressed I am with your site. I have placed two orders with your company before the change and a couple more after, and have received them all within a couple of day ( usually two ) after ordering. Very cool!! Thank you so much.

“Hey read about the Kaged Muscle PRE-KAGED and RE-KAGED workout & recovery combo, tried it and this stack really rocks for me. You know your stuff, and I believe you actually test products, because you've been doing reviews longer than any of the others. Keep goin guys, keep going!”
