      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.

      If you or your health care provider have any questions, please call: 1-800-898-5153. This product is manufactured to be within all acceptable industry variances. Manufactured in the USA with foreign and domestic components.

      GF-9 Natural human growth hormone is a great product.
      GF9 is a great product that I have cycled on and off of since 2015. I been using them because they help with energy, fat burn, and lean muscle for me. I'm 50 years old now and I still use this product. I do recommend. , because it has not failed me. It seem to help me stay in my military shape and form.

      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.

      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?

        I've been taking it for about 6 weeks without changing my diet or workout routine and haven't really seen any body fat reduction.
      I'm 47 so I don't know if that has any affect on results.

      Does this product actually work?
      A shopperJun 11, 2014

        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.

        I have been taking it for awhile and I honestly don't think it's worth the price. I haven't noticed any difference in my skin or other health factors. If it were less expensive I would say that it doesn't do any harm, but at its current price it's not worth it.

      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

        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

        No, it didn't unfortunately :-( I just don't think the ingredients are quality enough. Best recommendation high quality vitamins (Garden of Life), couple veggie smoothies a day add Amazing grass SuperFood powder to it (actually really good) and easily digestible foods, you'll feel better and loose the weight that growth factor claims. You can get all above from Vitamin Shoppe. Best of luck!!
