About Growth Factor-9

Based on more than 30 years of research, Growth Factor 9 is a dietary supplement that is claimed to boost natural HGH by a mean of 682 percent, and to “unleash your total performance and anti-aging potential.” In addition, Growth Factor 9 is claimed to be a clinically tested, maximum strength formula that can help strengthen joints and bones, reduce wrinkles and other signs of aging, increase libido, enhance your mood, and more.

Unfortunately, HGH is notoriously difficult to “trick” your body into producing naturally, which is why one of the only effective methods currently available is through injections by your physician. But does the clinical evidence provided by Growth Factor 9 change all of this, or does it just amount to marketing hype?

How Growth Factor 9 Works

According to the Growth Factor 9 website, human growth hormone (HGH) is a single chain peptide hormone that enters fat cells and causes them to shrink, while also entering muscle cells and stimulating growth. While the most effective method of increasing HGH within your body was previously through injections at your physician’s office, Growth Factor 9 claims to use a proprietary combination of amino acids that can encourage your pituitary gland to naturally increase your body’s own HGH levels.

As a result, Growth Factor 9 claims to be the first and only oral compound clinically proven to elevate the natural production of HGH by a mean of 682%, resulting in increased lean muscle mass, reduced body fat, increased endurance and recovery, improve mood, sleep, skin tone, and sex drive, and more. In order to accomplish this, Growth Factor 9 is claimed to include the following ingredients:

  • SeroVital 2.9 g A Proprietary Blend Containing: L-Lysine HCl, L-Arginine HCl, Oxo-Proline, N-Acetyl L-Cysteine, L-Glutamine, Schizonepeta (aerial parts) powder.

The manufacturer claims that Growth Factor 9 works for men and women, regardless of age. In order to begin experiencing the benefits, you’ll need to take 4 capsules on an empty stomach and not eat anything for 2 hours. Alternately, you can take it at night at least 2 hours after your last meal. However, Growth Factor 9’s manufacturer specifically states that you must continue exercising regularly and adhering to a healthy diet while taking the supplement.

Growth Factor 9 Pricing & Refund Policy

Each bottle of Growth Factor 9 contains 120 capsules (a 30-day supply), and is priced at $99.

If ordered directly through the manufacturer, you can sign up for the VIP Subscription during checkout, which means you’ll receive a discounted price of $80. In addition, you’ll also continue receiving a new bottle of Growth Factor 9 once every 30 days, and your credit card will be billed $80 each time.

Growth Factor 9 comes with a 30-day refund policy, less S&H charges (see more about this in the final section). In order to cancel your autoship program or to begin the refund process, you’ll need to contact customer service at 800-898-5153.

If you’d like to purchase Growth Factor 9 from a third-party retailer, the supplement is also available through BodyBuilding.com’s store, GNC, VitaminShoppe.com, and others.

Can Growth Factor 9 Really Help Boost Your HGH Levels?

With all of this in mind, what can you reasonably expect from a dietary supplement like Growth Factor 9—boosted HGH levels or just a lighter wallet? To answer these questions, consider the following:

Clinical Proof for Claims

First, although the Growth Factor 9 website does reference a clinical study to back up its claims (Study ID Number: PBRC10043 – found here), there are no results posted. This means that, although we can verify that the study took place, there is no way to verify what its outcome was.

Regardless, keep in mind that if an oral supplement were conclusively shown to increase HGH levels in humans, this would be considered a huge medical breakthrough, and would be made news throughout the world.

What’s Going on with SeroVital-hgh?

Next, the only ingredient contained in Growth Factor 9 is SeroVital-hgh, a proprietary blend of amino acids. If you read our review about this product, you’ll notice that this is a topical anti-aging treatment manufactured by Sanmedica International, which is a completely different company than manufactures Growth Factor 9. However, the pricing is identical, even down to the reduced price for signing up for the autoship program.

While it’s disconcerting that two different companies can sell two different supplements under two different names, as we mentioned in our original review, the Federal Trade Commission states: “There is “no reliable evidence to support the claim that over the counter products have the same effect as prescription HGH.”

Company & Product

Finally, growth Factor 9 was created by Novex Biotech based out of Salt Lake City, UT, who holds a C- rating with the BBB, despite only having 1 closed complaint. Interestingly enough, this complaint referenced Growth Factor 9 and extreme difficulty obtaining a refund.

This is important to note because, other than failure to work, difficulty obtaining refunds was the most common complaint we encountered during our research. Other common complaints included grogginess/difficulty waking in the morning and high price.

Bottom line

Between Growth Factor 9’s fuzzy clinical trial results, it’s high price, and it’s mixed online customer reviews, you may want to save your money and speak with your physician about legitimate options for increasing HGH levels.


  • Claims to be clinically proven to boost natural HGH by a mean of 682 percent.
  • Claims to help strengthen joints and bones, reduce wrinkles and other signs of aging, increase libido, enhance your mood, and more.
  • 30-day refund policy.


  • Results for clinical study not available online.
  • Appears to be an identical product to SeroVital-hgh, although the latter is an anti-aging topical solution.
  • Most common customer complaints reference failure to work, difficulty processing refunds, and high price.

    I am almost 70 years old. I started taking Factor-9 about a year ago. I look like I am in my 30s. When I go to the gym people are staring at me like "I own the gym." My hair has turned from white back to brown.

    Bottom Line: Yes, I would recommend this to a friend
