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.*

I would give the product itself 5 stars but the company 1star. Every bottle I have bought has been short at least 1 pill and, in one case, 3 pills. Called to notify them twice and received no satisfactory response.

Happy GRRRL ????
I LOVE this stuff!! I’m on my second cycle of taking Factor 9. It’s doing everything it said it does. I have more energy, endurance, better overall mood, my weights are going up in the gym 5-10# weekly and I’m staying leaner hen normal with less effort in controlling my carb intake. As a competitive physique athlete, this is now a staple supplement for me.

AND!! Because I tend to stay pretty lean on this stuff, like sub 15%, an additional surprise benefit was my chest size increased from a small B cup to a full D cup by the 3rd week!!! Woohoo!

Body aches and pains gone
I'm 39 years old and started having very odd aches and pains and knee swelling about a year and a half ago. The Orthopedists and Rheumatologists were confused. They could see the symptoms but they didn't know what was causing it. I was tired of taking naproxen just to not be in pain, and even that wouldn't help all that much. I saw a commercial for Growth Factor 9 on TV and looked it up at GNC and took the risk to see if it would help. To my surprise I'm now 99% pain free. I can run and jump again, two things which were impossible for nearly two years. Maybe I'm just lucky, but I would recommend trying this before giving up hope.

I took this when I had to go on runs with my unit and it would take a little bit to hit but when it did I felt amazing, my endurance increased and had much more energy. And when I forgot to take it I definitely noticed I felt more drained and fell back from the guys that I usually passed up.
