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.*

Works for me.
Product was recommended by a friend.. I have had awesome gains since I started taking it! Sometimes you have to find the right product that works with your body, this one works perfect for me! Someone actually said they thought I was on a cycle my gains were so noticeable!

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.

Revitalized at 50
By the 11th day I realized my energy and brain fog was gone and it wasn't just a one day fluke. I feel I have my life back and I am out of isolation.
All premenopausal/Fibromyalgia women should try. You have nothing to lose. Miracle for me!

Great product
I take it at night. You have to wait 2 hours after you take your last bite . That is not so easy some times. I do sleep much better. I am 77 years old. I do have more energy. I will keep taking it. I have been on it for 2 months. I will take it for at least 2 more months just to see if I keep my energy level up.

It works!!!
After reading every review I could find during the course of a month, I decided to purchase the product. I have been taking it for 7 short days. I can attest that it works! I work out with weights in the gym and have had a hard time getting over my plateau. This has given me the extra boost I need to go the extra mile in the gym. I work midnight shifts so sleep proper sleep has always been an issue-- not in the last 7 day. I feel amazingly youthful and energized. I have had little to no muscle soreness at all and I workout a lot with weights. The recovery process is undeniable. Also in just a week, I am beginning to see the formation of my abs peaking through and I have not added any additional ab work. On the scale I have dropped one pound but I feel its actually more due to the little muscle growth I can see and measured (muscle weighs more). Did I mention how wonderful and glowing my skin is???Some are skeptical because of the price but I care more about the results. I have wasted ten times that much on there products that I've thrown away that don't work at all. I cant wait to see even better results as time moves along. I would suggest taking at night only because I get up early and 2hrs is so long for me to wait to have breakfast after I take them.

Factor 9
I have been on factor 9 for about 2 weeks now and I already see a change in the gym I'm not struggling to put up the weight. I think its a very good product and i would recommend it to anyone looking for an edge in the gym and looking to put on pounds.

Good results so far
Two weeks today and having better workouts, which is key; certainly not a miracle drug but it does boost your workout and I already see some muscle build and definition. I will say, it's somehow leveled my mood and sleep pattern. No issues falling asleep or remaining asleep.

Growth Factor 9
This product works but it takes time ( I have been on for 6 months) I have noticed a reduction in wrinkles and body mass (muscles) is slowly getting thicker . If you can afford this supplement I would recommend this product.
