About This Product

CLINICALLY TESTED
HUMAN GROWTH HORMONE SECRETAGOGUE
MAXIMUM STRENGTH FORMULA

Boost natural human growth hormone levels up to 682%.

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 blood samples were drawn over 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 hGH levels, and the results were independently analyzed. The results: the GF-9 blend led to a 682% increase in serum hGH levels at 120 minutes, which was significant above and beyond placebo.

GF-9 Much better than any product I have tried!

I have tried so many different products but FINALLY one that does what it says. Since taking GF-9 my muscle definition has become more noticeable and my muscle mass has increased. And I am 63 years of age. I thought my days of developing muscle were past but not so! This stuff is legit!

I started with a packet

I started with a packet in the morning and could feel the difference before my workout. For a change, I tried the capsules at night and felt great the next morning. Thanks for developing this product.

just wanted to know should i cycle Growth Factor-9 ??

mohamed s.Mar 16, 2013

Best Answer: It probably would not hurt to cycle . . . I take six capsules a day for five days, and off two. No adverse side effects.

June J.Dec 2, 2018

I am 15 years old and i am 5'6, my dad is 5'7 and my mom is 5'8. I know I am not completely done with growing, but I think I might only grow a few more inches. If i start taking this supplement, will it increase my height to possibly 5'10 and if so how long would that take?

Sawyer K.May 21, 2015

does it work?

A shopperDec 1, 2014

Best Answer: Nope, and it makes your hair fall out too.

help burn fat ?

everett pMay 12, 2013

Best Answer: No, this is a supplement for mass/muscle building not fat burning.

Kenneth CMay 12, 2013

Does this product actually make you grow taller, it says it suppose to help bone growth?

A shopperFeb 4, 2015

Best Answer: It did not increase my height and i have not noticed any increase in bone density

JamesFeb 4, 2015

Hey! I was wondering if you noticed any increase in your height after taking Growth Factor 9? If you could let me know, that would be great. Thanks!

rachelle f.Dec 2, 2014

Best Answer: Nope no increase in height. Honestly didn't think this product did much for me at all. Hope this helps!

Brandon WDec 7, 2014

Does this product actually work?

A shopperJun 11, 2014

Best Answer: Don't have unrealistic expectations for this product. If you take it consistently for months you may see improvements overall. I use it primarily to maintain weight and burn fat (and I am not overweight). It's a maintenance issue. If you stop taking it, as I did recently to see if it made a difference, I immediately put on a few pounds. Whatever it does, it helps. I also think it helps my skin. I'm in my 60's but look 15-20 years younger.

Karen CJun 12, 2014

Does this product make you grow taller ?

A shopperJul 7, 2015

Well, the obvious question is has it been up to its hype?

Charles FOct 4, 2013

Best Answer: I think it did, although I have no data to prove it. Just from looking at myself in the mirror each day for the month that I took it, I feel like I dropped some body fat and felt more energized. I worked out about 3-4 times per week (mixture of running, basketball, and boxing) while on the cycle, so I feel like that also played a role. I'd give it a shot if I were you. I also think that two-three cycles of this would definitely yield better results. One month usually isn't a long enough time frame to really see drastic changes no matter what you're changing in your daily lifestyle. Hope this helps
