Product Information



In a recent, randomized, cross-over, double-blind clinical trial, men and women between 18 and 70 years of age were recruited. Subjects were scheduled for two testing sessions a week apart where, after an overnight fast, blood samples were drawn over a period of 120 minutes after consumption of either the proprietary Growth Factor-9 blend or placebo capsules. Neither the subjects nor the investigators knew at which session the subjects received the GF-9 blend and at which session they received the placebo. At the end of the study, the samples were tested for serum hormone levels, and the results were independently analyzed. The results: the GF-9 blend led to a 682% increase in serum hormone levels at 120 minutes, which was significant above and beyond placebo.*

Best Supplement Husbands Ever Tried !
I was looking for something to give my hubby for his birthday, he likes to workout. but it always seems he runs out of energy, So I took it upon myself to buy this for him. Best birthday present ever !! his energy levels have never been better. He also tells me he is sleeping better. We had problems in the bedroom some times. But now since he has been taking this for 3 months its even better there too.. Whoever came up with this product, Thank you, its has changed his life !!

Just what i was looking for!
This stuff is awesome! I was reluctant to try it because i didnt want to waste my money but with their money back guarantee, i figured why not. I followed the instructions and it wasn't long before i started to notice better sleep and energy. A few weeks went by and I felt like i was working out even though i wasnt. That was two years ago and ive been taking it ever since. I'm in my 50's now and only looking forward!

Great Product
I was skeptical when I discovered this product but decided to give it a try and I am glad I did. It definitely works for anti-aging. I have pulled gray hairs out of my head and you can see the hair near the root is black again.

No other supplement has been as consistently effective as this one. By the end of the cycle, my abdomen felt like a slab of muscle. My endurance was freaky, I was working out every day at my job and barely feeling it. Of course, after the thirty day cycle, I slept for fifteen hours at a stretch, but that's the price you pay for abnormal performance. And I don't even go to the gym.
