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 have been taking this supplement for about a month now, I have noticed a drastic increase in size and my ability to run faster has been improved dramatically. When used with an appropriate diet and the instructions are followed it works. Results do vary from person to person so your experience may not be as great as mine.

Usage discipline.
I know it's working as advertised. I need to be more consistent with my use per the directions on the bottle in order for it to be more effective for me. I have seen results even when I use it 80% of the time.

Seems Ok
It's only been about 3 weeks. Feel a little more cut and leaner, but scale isn't showing much. Not sure If I prefer this or the Nugenix, might give it the full two months to see.

So far so good.
Im 52 and started working out to reverse type 2 diabetes. Ive lost 36lbd in 7 months, but have not grained muscle how I had hoped. I bought this product on the advice of a co worker. Im 2 weeks in and have noticed a change in my workouts. I can push harder longer already. Ive been sleeping like a baby. My buddy told me to wait until week two and I’ll see the shred effect. I think if you put in the time, follow a good diet. This stuff is for real. Happy so far. Oh and in case you are wondering. I have no singa of being dievetic any longer.

I bought my first bottle thinking it would help lose belly fat. They tell you it may take 60 days to take full effect so I bought another. I haven't had any improvement regarding belly fat, but I do have more energy and better sleep.

Didn't work for me.
Didn't work like I expected. I noticed that a lot of the positive reviews are from people who have been taking it longer than a month. I only took for twenty-five days. Maybe I need to take it longer but is pricey. Disappointed that the bottle was short on the amount of pills it was supposed to have. Just by two pills but still less than what they say on bottle.

Will I grow taller by taking this?
A shopper on Jun 27, 2016
BEST ANSWER: If your growth plates are still open, the added HGH levels should, in theory, produce more IGH-1, which is responsible for the lengthening of bones. Even if your growth plates are closed the supplement can still increase the height of cartilage in your spine, which should make you taller.
