Growth Factor-9 is a hormone booster, according to the product description on GNC, but at first glance there is no mention of the hormone the supplement is supposed to increase. We assume, based on the product’s name, human growth hormone or HGH is the hormone the company is referring to, but we did not immediately notice any mention of HGH. We did immediately notice the $100 price tag, which either means the product is packed with expensive ingredients or the company is hoping the buyer will look at the claims and hit the Add to Cart button without questioning the ingredients.

List of Ingredients

  • L-Arginine HCL
  • L-Lysine HCL
  • N-Acetyl L-Cysteine
  • L-Glutamine
  • Oxo-Proline
  • Schizonepeta Powder

Product Features

The first four ingredients are nothing special and certainly not worth the $100 price tag. The dieter can find l-arginine, l-lysine, n-acetyl l-cysteine and l-glutamine in a long list of bodybuilding, diet and protein supplements. If Novex Biotech, the makers of Growth Factor-9, wants to convince the consumer to spend that much money the last two ingredients better have a strong clinical background.

Oxo-proline, also referred to as pyroglutamic acid, is a rare amino acid. We found no clinical studies supporting any health benefits of this ingredient, but we did find mention of at least one case of 5-oxoproline acidosis in patients with long-term use of acetaminophen. We also found reference that oxoproline may be used on the skin to hold in moisture.

Schizonepeta is an herb commonly used to treat the common cold and skin conditions like eczema. There are no health benefits even slightly associated with growth hormone production, according to WebMD.

  • We found all the ingredients listed for Growth Factor-9.


  • The supplement is overpriced.
  • None of the ingredients are associated with growth hormone production.
  • Growth hormone is never mentioned.
  • We were unable to find the clinical study supporting increased serum hormone levels.
  • The reviews mention weight loss, increased lean muscle, fat loss and improvements to sleep – none of which are listed in the product description.


We are quite confused by this supplement. The reviews are mixed and none of the literature names growth hormone. There is mention of a serum hormone, but not serum growth hormone. The clinical study referenced in the product description and on the product label is impossible to trace and there is no link to where the study was completed or published. We suggest dieters choose a different product for weight loss as we are not completely sure what this product is designed to do.

    The last time I bought a product from you I never got what I paid for, I never complained. ’cause it’s just $4.95 but what I don’t understand why you have to go ahead and deduct another $93.95 from my account without prior notice.
    Right now what I want is refund of my money and I do not want your product. If you have sent it it’s better you call it off and refund my money.
    Thank you
