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.

A spring in my step & Sustained energy.
I've been on GF-9 Black Label and OxyDrene for a couple of months, and yesterday was when it really hit that the benefits and positive impacts were noticeable. OxyDrene immediately had a noticeable effect - I can power up and really crush workouts, especially at the tail end. But more broadly, I wake up with more energy and focus to get s**t done. I naturally want to take the stairs up to my fifth floor office - and I'm jogging up those stairs. The daily rhythm feels supercharged. And I'm here for it.

GF-9 Review
I've been using GF-9 for over a month now. I can say with certainty that I'm a big fan of this product. It is helped me with my focus in the gym, performance in the gym, and muscle growth. I'm extremely satisfied with the product and will continue to use it as long as I can find it on the shelves. I would recommend this product to all my friends who lift and who are looking for all the same benefits I've received.

While I've only been on this for 30 days and just started month 2, I do notice that my muscles seem more dense. This product also seems to give me energy after taking it in the morning.

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

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.
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?

A shopper

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

help burn fat ?
everett p

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

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

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

James
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.

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

Brandon W
Does this product actually work?
A shopper

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 C
Does this product make you grow taller ?
A shopper
Well, the obvious question is has it been up to its hype?
Charles F

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
