Growth Factor-9

Athletes, bodybuilders and fitness enthusiasts are often looking for new ways to master that competitive edge, shaving seconds off of a personal best or shortening recovery times so as to spend more time doing what they love. The kinds of supplements that typically make this possible are amongst the most dangerous, expensive and illegal solutions out there, often requiring dodgy dealers and intravenous injections. In this market, a relatively safe, cheap and available product could work wonders, offering the same boost for a fraction of the risk.

Below we take an in-depth look into Growth Factor-9, to see whether this unique amino acid blend offers real results to justify its continued high price tag.

  • Relatively few side effects
  • 30-day money-back guarantee

Growth Factor-9 Cons

Growth Factor-9


What You Need To Know About Growth Factor-9

Growth Factor-9 is a sporting and bodybuilding supplement that promises to raise the levels of natural Human Growth Hormone (HGH) in the body. It works via a patented and well-documented process using amino acids, all of which work together to stimulate the pituitary gland to produce and release more HGH naturally. Curiously, this ingredient mix appears to be identical to that of an earlier product called SeroVital, which was marketed as an anti-aging supplement.

Although the original SeroVital formula was produced and marketed by a company called SanMedica International, the Growth Factor-9 version is marketed by a different manufacturer called Novex Biotech. Growth Factor-9 appears to be Novex Biotech’s flagship product, and has attracted interest from the Obesity Society and a number of Internet retailers and reviewers.

What Are The Side Effects Of Growth Factor-9?

The main reported side effect of taking Growth Factor-9 according to customer reviews is that it causes sleepiness and fatigue. Some of the other ingredients in the mix can also cause stomach pain and diarrhoea (particularly lysine and arginine). In rare cases, arginine can also cause low blood pressure, respiratory issues and other miscellaneous allergic reactions. N-Acetyl L-Cysteine has been known to cause nausea, diarrhoea and constipation, and has occasionally lead to rare but severe side effects including rashes, fever, headaches, drowsiness, and low blood pressure.

How Much Does Growth Factor-9 Cost?

The price of Growth Factor-9 appears to change depending on where you buy it. The cheapest price we found for the product was $79.99 plus free shipping on, and the most expensive was $99 plus $6 shipping on the official Novex Biotech website. Both prices are for the standard container of 120 capsules. Always shop around to find the best deal!

Our Verdict On Growth Factor-9

Growth Factor-9 has received a surprisingly mixed reception from customers for an ingredient mix that appears to be well backed by scientific evidence. Despite the evidence of a double-blind, placebo-controlled study that “proves” Growth Factor-9 works, around half of the legitimate reviews on were wholly negative. Many of the reviewers are experienced bodybuilders and fitness enthusiasts, the kind of customer that’s extremely in-tune with changes to their performance. With so many reporting that the product is useless, we can only conclude that the product may only produce results in circumstances where the body was deficient in HGH already.

To make matters worse, the product appears to be a simple, rebranded version of an entirely different product that was marketed on entirely different lines. As the ingredients lists are clearly identical, we can only conclude that the intended use of this blend is unclear to even the marketers.

On the plus side, this product is relatively free of the dangers, high price tags and illegal nature of many of the bodybuilding world’s alternative supplements (such as risky and illegal steroids). At the very least, we can say that this product is relatively free of side effects, and is backed up by a 30-day money-back guarantee that invites customers to give the product a risk-free try. However, these points are all moot if the product will not work for half of its user base!

We do not recommend Growth Factor-9 to our readers.

Growth Factor-9 Review

Growth Factor-9 is a complex bodybuilding product that acts as a growth hormone. The product is mainly marketed toward the bodybuilding and athletic performance market, although the advertising copy acknowledges that the mixture is considered so strong that it is marked as a banned substance by professional and amateur sporting authorities. Curiously, the mixture appears to be a rebranded version of a previous anti-aging product called SeroVital HGH.

Growth Factor-9 Facts

  • Manufactured by Novex Biotech.
  • Contains 120 capsules per bottle.
  • Growth hormone supplement.

Growth Factor-9 is sold by Novex Biotech, a sporting manufacturer based in the USA (although the original Serovital HGH formula is owned and marketed by a different company called SanMedica International). Although Novex Biotech appears to have a number of testosterone and bodybuilding supplement, Growth Factor-9 is by far their most popular and well-promoted product. The company can be easily reached via the email address listed at the top of the website.

How to Take Growth Factor-9

Adults take 4 capsules by mouth on an empty stomach, either in the morning two hours before breakfast or two hours after dinner prior to bedtime. Do not exceed 4 capsules in any 24-hour period.

Growth Factor-9 Concerns:

  • Some customers complain that the product doesn’t work.
  • Product is regarded as illegal by most professional and amateur sporting bodies.
  • Product is very expensive.

What Does Growth Factor-9 Claim To Do?

The product is intended to raise the levels of Human Growth Hormone (HGH) in the body, which will help bodybuilders and athletes to build muscle faster with quicker and more painless recovery times in-between sessions. The way that Growth Factor-9 works is slightly different when compared to other products, using an amino acid blend to stimulate the pituitary gland’s production of natural HGH.

Does Growth Factor-9 Work?

The manufacturers of Growth Factor-9 are proud of the clinical evidence supporting their claims about the product’s effectiveness. So far, one double-blind, placebo-controlled study has suggested that the product supports boosted HGH levels for participants of both genders and a range of ages. These findings have been spread by independent groups that are unaffiliated with the company, meaning that enthusiasm for the product does not appear to be misplaced.

That being said the evidence provided by the current customer base provides a more mixed picture. Although some claim that the product works as advertised, we estimate that around 50% claim that the product does very little or nothing at all. Many of these customers also appear to be experienced bodybuilders who carefully monitor their daily activity and results. The conclusion appears to be that the product may boost HGH levels, but whether that will help an individual to achieve better results in the gym may still be up to their personal circumstances.

What Are The Ingredients of Growth Factor-9?

The ingredients contained within Growth Factor-9 are listed below. Readers should note that the quantities of the individual ingredients are not listed at all, making it hard to estimate the effectiveness of the overall mix. As 2900 mg is listed on the packaging, we have assumed that this figure corresponds to one serving.

SeroVital HGH Proprietary Blend 2900 mg

  • L-Lysine HCI: Lysine is an amino acid that is sometimes used to improve athletic performance (although little evidence exists to prove whether it is effective in isolation).
  • L-Arginine HCI: Another amino acid, arginine can be readily converted into nitric oxide. This has the effect of widening the blood vessels, facilitating more efficient blood flow. It also stimulated the release of the growth hormones and insulin.
  • Oxo-Proline: Proline is used to break down proteins for use by cells in the body. Supplementing it is thought to help with maintaining muscle tissue and combating joint and tissue strains. Deficiencies are rare for people with normal diets.
  • N-Acetyl L-Cysteine: This amino acid and antioxidant is often used to combat the effects of various respiratory and bronchial diseases. It has also been used to treat sports injury complications, although no clinical evidence exists to prove its effectiveness in this regard.
  • L-Glutamine: An essential amino acid, which is a building block of protein. It is the most abundant free amino acid in the body, and is produced in the muscles and distributed where it is needed via the circulatory system.
  • Schizonepeta Powder: Schizonepeta is thought to enhance the immune function in the body, and has been used to treat a range of illnesses. No evidence exists to prove that it does anything.

Does Growth Factor-9 Have Any Side Effects?

Some of the ingredients contained within the mix may cause side effects, and some side effects have been reported by customers – particularly sleepiness and fatigue.

L-Arginine may cause some intestinal effects, including abdominal pain, bloating, and diarrhoea. It can also occasionally cause low blood pressure, asthma-like symptoms, airway inflammation and allergic reactions. L-Lysine sometimes causes stomach pain and diarrhoea. N-Acetyl L-Cysteine can cause vomiting, diarrhoea and constipation, and in rare cases has been known to cause rashes, fever, headaches, drowsiness, and low blood pressure. Some of the ingredients contained within Growth Factor-9 can cause liver damage when taken in very high doses over time.

Do not exceed suggested daily serving. Not for use by individuals under the age of 18 years. Do not use if pregnant or nursing. Use only as directed. Keep out of reach of children.

Are There Any Customer Reviews For Growth Factor-9?

Some detailed independent customer reviews for Growth Factor-9 can be found on, where an active community exists to discuss products like these. Opinions on Growth Factor-9 seem to be split 50/50, with some stating that the product revolutionised their gym routine, and others complaining that the product did nothing. Readers should note that many of the positive reviews for Growth Factor-9 on appear to have been blatantly faked by the company.

I have followed the directions exactly… I have shed almost all of my body fat, and I have built lean muscle. There is a definite (positive) difference in my energy levels, my ability to exercise, and my ability to recover. If you purchase this product… You have to be willing to FOLLOW THE INSTRUCTIONS… Growth Factor 9 worked for me. I’m sure it’ll work for you, too, if you use it properly.

I read comments on this product of it not working, well I’ve tried most of the supplement’s out there and let me tell you it does work. It did give me some anger issues, but channelling it to my workouts has increased my bench in less than 10 days up 20 lbs. It works!!!

I thought that being over 40 I would be the best candidate to see the results they’ve claimed it should deliver. Little did I know… I’ve experienced nothing with the exception of me sleeping like a baby for a month every day. No pump, no fat loss, no strength gain, no improvement with post-workout recovery, etc. Maybe it works for some people, maybe it is all in our heads at the end, but I will certainly not going to spend $100 to buy it ever again. Waste of money. Complete waste of money from my experience.

This product did nothing. Complete SCAM. Look at all the profiles of the reviewers. Accounts just made to boost its ratings.

Does Growth Factor-9 Offer a Money-Back Guarantee?
