"After seven years in the NFL, it was crucial I find a strength and conditioning program that would give me an edge on the younger players. After researching many of the best program, I can say with confidence that the Big Beyond Belief program is the only one that combines scientific data with old fashioned common sense. This program gave me results I thought unachievable, along with my most productive years in the NFL."
Michael Young

"I started prior to a contest in May and by June of the following year I was 13 pounds heavier (contest weight after cutting) and a lot harder! Hard enough to win my first over-all title, since then my gains continue and I'm getting bigger and stronger in all my lifts!"

I used to believe that I was a "Hard-Gainer." Boy was I brainwashed by a self-protective supplement market. I have put on over 20 pounds in only 13 weeks. That's more than in the last two years total. I would say, if you don't want to try this system, you don't want to grow.

"As a college football player I was always strong but had trouble putting on the kind of size I wanted. After listening to Leo's advice it was like breaking through a wall, I put on over 10 pounds of lean muscle in only a few months."

"Over the years, I've seen a number of companies come and go, making wild claims about their programs. When tried, they produce more frustration than muscle. If you follow the Big Beyond Belief program to a 'T', you will gain a tremendous amount of growth."

"In 14 years of training, I was always referred to as a natural lightweight of 154-165 lbs. in bodybuilding, powerlifting, and Olympic lifting with an off season weight of 171 lbs. and 13% body fat. Since starting with the Serious Growth System I carry an off season weight of 184 at 11% body fat, I fully expect to cut up for my contest this summer at the Middleweight limit of 176 lbs."

"You've got to be freakin kidding me! I'm growing like a newborn baby. Big Beyond Belief is un-freaking-believable! My strength is taking off to another solar system. Everyday I look and feel better, I owe it all to you guys. Thanks a million. If you ever need a favor, I'm in debt to you for life.
