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.*

First product that has actually worked
I'm not a big fan of most supplements. Most are junk that are laced with caffeine and sold at high prices with no proof they work (and no FDA oversight). I was working out, but not eating real well and not losing weight. I decided to try this out of desperation, and the weight began to fall off within the first two weeks. I feel leaner and stronger. Four weeks in and I have already lost 10 lbs with almost no change in diet or exercise. I am planning to continue buying this, even though I think the price is too high. So far, given the results I have seen, I think it is worth it. Also, no jitters, drowsiness, etc. You wouldn't even know you took it except for how your body is changing. Hard for me to admit, but I think this one may be legit.

Amazing results!!
I heard about this product from a friend and also I did my homework on it. Everything I read about it was pretty good so I bought it a week ago. I take 4 pills every morning 2 hours before breakfast, I'm eating my regular diet and working out 6 days a week and I can see results already, I'm getting lean! Faster recovery. Also I have notice I don't feel tired in the morning anymore and I fall sleep very easy at night. My mood it's better and my skin it's glowing. I'm in love with this product!

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.

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.

I take this product every morning around 7 a.m. My mood improved a whole lot. My performance is incredible. I can do more in an hour than I could before. There are no side effects like other products I have used and I get really drowsy and moody. This product is the complete opposite, no drowsiness or moodiness. It has only been about three weeks and I am seeing better definition and muscle growth, and no sign of tolerance to the product (I don't feel the need to up the dose because of lack of performance) GREAT PRODUCT!!! I LOVE IT!!!

Giving it a try
I wasn't sure if taking some pills would do anything for me, but I was feeling lethargic and had gained weight over the last two years. I'm 6'3" and gone from 205 to 242 lbs. I've been taking Growth Factor 9 for almost a month and I feel more energy on a regular basis. I've also changed my diet and working out 4-6 days a week like I used to, so I can't say for sure that these pills added strength, but I can say I feel like they've given me more energy and I've dropped to 230 lbs. I'm going to keep taking this product.

I will buy this product again and again
This product is great. It really works. I am not really one that works out but I know a few that do. For me it helped me concentrate and survive some long hours at work. I also got smoother skin and more muscle tone. I liked it so much I started selling it.
