How Did Growth Factor 9 Start?
For a company that has been around for 13 years, there is virtually no information available about Novex Biotech, the company behind Growth Factor 9 supplement. 
Growth Factor 9 Claims
There are a lot of claims made about the Grow Factor 9 product.
“Growth Factor-9 is the first – and only – oral dietary supplement that works with your own body to enhance growth hormone levels by up to 682%”. Novex Biotech says it has the science to prove the claims that Growth Factor 9 boosts the building of lean tissue while reducing fat in athletes and bodybuilders.
Interestingly, the companies own scientific study says, “evidence of whether oral amino acids stimulate growth hormones is unclear”. 
“Unleash Your Total Performance… and potential with Growth Factor-9, our first – and only –supplement suggested to support the natural production of HGH in both male and female, young and old.” While they make this claim, there are mixed reviews from users and there is no scientific evidence that Growth Factor 9 ‘unleashes your total performance’. 
Growth Factor 9 Ingredients
Growth Factor 9 is formulated from the SeroVital HGH blend which has the following ingredients:
The HGH supplement Growth Factor 9 appears to be a rebadged version of the SeroVital blend. According to the HGH Growth Factor 9 label, it is made with the SeroVital blend. And, the supplement facts on both labels are identical. So, what is the SeroVital blend?
SeroVital is supposed to help increase human growth hormone (HGH) when taken orally and combined with regular exercise. It is also being hailed as the next best thing for its anti-aging properties.
Ever since the human growth hormone was endorsed by Dr. Oz in 2012, this product has been popular. It claims to help you:
• grow muscle and burn fat
• speed up recovery from injuries
• delay the aging process
• heal brain injuries. 
The amino acid glutamine naturally occurs in our bodies. It is produced in our muscles, and the bloodstream distributes the amino acids to the organs that need them. It can help your immune system, the functioning of the gut, and other functions of your body especially during periods of stress. Glutamine also provides energy to different cells in your body and it assists in the production of other chemicals in the body.
During times of stress (after surgery, trauma, injury, chemotherapy, etc) your body can use more glutamine than your muscles can produce. When this happens, there is muscle wasting as seen in HIV/AIDS. Glutamine supplements can help. 
L-lysine is another amino acid used in the making of medicines and supplements. It is usually used to prevent and treat cold sores. It is taken orally or applied directly to the affected area. L-lysine is also taken by people to improve their athletic performance. But, there is insufficient evidence to know whether it works in this way or not. 
There is currently little known about oxo-proline, which is a glutamic acid derivative. Research is in progress about the role of oxo-proline in the regulation of neutral amino acid transport across the blood-brain barrier. But, the research is mixed, and studies on animals show oxo-proline may have a negative effect rather than a positive one.  
When growth hormone supplements have oxo-proline among the ingredients, it usually comes from glutamic acid. There have been a few trials of glutamic acid with hypotheses that it has a positive impact on the human growth hormone that your body produces naturally. But it is still not known whether oxo-proline has a direct effect on growth hormones or not. 
L-arginine is an amino acid needed for the body to produce proteins. It occurs naturally in foods such as dairy products, fish, red meat, and poultry. It is also lab made and used in supplements and medicines. When taken, the body changes L-arginine into nitric oxide, which improves your blood flow by widening the arteries. It can also trigger the release of insulin, growth hormones, and other things in your body.
It has wide and varied benefits including preventing the common cold, heart and vessel conditions, men and women’s sexual problems, and topically as a wound healer and to simulate blood flow in cold hands and feet. 
N-acetyl cysteine is another amino acid that is thought to be useful as a supplement. It is commonly used to treat Tylenol and carbon monoxide poisoning, and as an antioxidant it may prevent cancer. The use of N-acetyl cysteine medically is varied. For example, it is used to treat epilepsy, ear infections, complications of kidney disease, and to prevent liver damage caused by alcohol. 
Schizonepeta is a plant also known as Japanese Catnip. It can help with heavy menstrual periods, skin conditions, colds, sore throats, and fever when mixed with other ingredients. WebMD says further evidence is required to prove its effectiveness for these issues, and the research into its benefits is mixed. 
Growth Factor 9 Side Effects
Possible side effects of human growth hormones include
- swelling of body tissues
- muscle, nerve, and joint pains
- carpal tunnel
- high cholesterol
- tingling or numbness of the skin
It can also promote the growth of cancerous tumors and may increase the risk of diabetes. Get the advice of your healthcare provider before taking human growth hormone supplements not prescribed by a doctor. 
Glutamine is likely to be safe for most people when taken in doses of up to 40 g a day orally, and 600 mg per kilogram of weight intravenously. For people with cirrhosis, (a severe liver disease with confusion, mania, and seizures) glutamine can make these conditions worse. Note that the effectiveness of glutamine has not been medically proven. 
L-lysine is mostly safe for people who take the manufacturer’s recommended dose for a period of a year, and when applied topically to the skin in the short term. Side effects can include diarrhea and stomach cramps.
Do not take L-lysine without consulting your doctor if you have kidney disease. There is some evidence that taking supplements that contain this ingredient over a long period of time, and in high doses, can cause kidney disease, even in previously healthy people.
Avoid supplements with L-lysine when pregnant. There is not enough research about whether it is safe to take while pregnant.  [https://www.livestrong.com/article/501936-l-lysine-warnings/]
Research is lacking on this ingredient. There are suggestions that taking too much oxo-proline can elevate your amino acid intake and cause extra stress on the kidneys and liver when dispelling the extra waste from the body. Before taking any supplement containing amino acids, check with your doctor if you have liver or kidney problems.
L-arginine is generally safe when taken in the short term. However, it can cause some side effects including allergies, diarrhea, abnormalities in your blood, low blood pressure, bloating, stomach pain, inflamed airways and an onset of asthma, and gout. If you are prone to any of these, check with your doctor before taking supplements like Growth Factor 9 that contain L-arginine.
If you have herpes, you should avoid L-arginine as it can cause the herpes virus to multiply and make the condition worse.
Because L-arginine can lower your blood pressure, you must stop taking it at least 2 weeks before any scheduled surgery.
It is usually safe for children in low doses. However, it can be unsafe when given in high doses and can cause the onset of serious side effects and possible death. 
N-acetyl cysteine is usually safe when taken as a prescription medication. It smells nasty and can cause diarrhea, constipation, vomiting, and nausea. Rarer side effects include fever, sleepiness, liver problems, rashes, headaches, and low blood pressure.
Do not use N-acetyl cysteine supplements or products when pregnant. There is not enough evidence to know if it is safe or not.
N-acetyl cysteine can cause swelling of the mouth, tightness in your chest, runny nose, sleepiness, and a clamminess when inhaled through the nose.
Avoid products containing N-acetyl cysteine, if you have a blood disorder or having surgery. It can interfere with the blood clotting process. Stop taking these products at least 2 weeks before scheduled surgery. 
Schizonepeta is generally safe for people when taken in low doses, but may harm the liver in high doses. Do not use this product if you have liver problems.
It is not known if it is safe for pregnant women, so it is best to avoid it during this time. It is difficult to understand why this is an ingredient in Growth Factor 9. 
Does Growth Factor 9 Work?
Whether the Growth Factor 9 supplement works or not is open to debate. Customer reviews are mixed about the results of taking Growth Factor 9.
However, something interesting we found: supplements that advertise their products as an ‘HGH release’ are unlikely to contain any true HGH.
These claims are often made by sports supplements but they have few or no scientific studies to back their claims. Although the companies are not directly violating FDA regulations, they rely on the studies done on the prescription HGH to support their HGH supplemental blends. 
Growth Factor 9 Benefits and Results
There is no proof there are any benefits from using Growth Factor 9. There is anecdotal evidence from customers, but that is a mix of negative and positive Growth Factor 9 reviews. One of the common negative comments is how expensive it is.
Growth Factor 9 claims its benefits include:
- the ability to build muscle more quickly
- improves your skin tone
- helps you sleep better at night
- improves your mood
- assists you to focus your concentration
- can help improve you sex life and libido
Details on Growth Factor 9 and Weight Loss
The only information we could find about Growth Factor 9 and weight loss is that its use will “help increase lean muscle mass, reduce body fat.” This is not a supplement you use to facilitate weight loss. It is for athletes and people looking to boost their physical performance and appearance. 
How to Use (Take) Growth Factor 9
To use the Growth Factor 9 supplement, take four capsules on a completely empty stomach at least two hours before breakfast or two hours after dinner before going to bed.
Warnings are to use only as directed and not to exceed the recommended daily dose. It is not for use for people under the age of 18 and keep it out of reach of children.
Growth Factor 9 Product Warnings
We could find no FDA warnings for Novex Biotech Growth Factor 9 in itself, but there are plenty of warnings about other products containing HGH. However, it is interesting to note, that although there are hundreds of companies promoting their supplements as containing HGH, it is illegal to sell products with HGH, including supplements, without a prescription. 
Any Growth Factor 9 Lawsuits?
In February 2015, a federal judge dismissed the lawsuit against Novex Biotech LLC and GNC Corp. The complaint filed in 2014 alleged the companies were falsely advertising Growth Factor 9 to provide a “682% mean increase in serum growth hormone levels” without the scientific evidence to support the claims.
Among the reasons the judge dismissed the case was the complainant did not produce any evidence or scientific studies that “disproved” the companies claim. The case was dismissed with prejudice, which means the complainant cannot file the lawsuit again.
Growth Factor 9 Alternatives
There are many Growth Factor 9 alternatives. Here are a few.
Reaction GH is made by the company M Theory and it has the science to back its claims. Its ingredients include Tryptophan, GABA, and arginine working together to enhance your muscle building goals or to help prevent aging. 
Invigorate HGH was specifically developed for aging men to support their weight loss and muscle gain, and to promote energy. It also claims to have a sexual vitality complex included in the formula to help increase men’s libido and to help maintain an erection. 
Universal Nutrition GH Stack
Universal Nutrition claims its product GH Stack works together with your system to produce natural HGH, instead of just sustaining it in your system. 
Novex Biotech Growth Factor 9 Reviews
It was actually difficult to find customer reviews, and it appears that HGH Growth Factor 9 is not sold on Amazon.
“I believe this is helping with size, stamina and recovery, but I am putting in the work five days a week. And….extra bonus…my hair seems to be growing faster and seems more full. Yes it is expensive. Yes I plan to continue.”
“I think the product did have a positive impact, but REALLY expensive for a “amino acid proprietary blend.” Capsules were easy to swallow – another plus. Real problem was timing of the dosage: have to take 4 capsules on an empty stomach 2 hours before breakfast, or two hours after dinner before bedtime. I work out in the afternoons, so 2 hours after dinner was out. I wake up late, so I found I was taking capsules at 10m and having breakfast at noon – or had to wake up early at 6 to have breakfast at 8: a royal pain. Product label said it ‘led to a 682% increase in serum HGH levels at 120 minutes’ – meaning my HGH peaked well before my workout. This product is probably best used by those who work out fasted in the morning, and can work out 2 hours after taking the product. Had a lingering cough that started shortly after taking this product the first time – was testing it again to see if it happened again, and (thankfully) it didn’t. Discontinuing use of it today, due to expense and fact dosage timing doesn’t work for my schedule.” -by Messineo
“It failed too I would recommend it to everyone that is not you buy this product.” -by Jarsi
I brought the growth factor thing and very delicately followed the instructions… having it on empty stomach was bit surprisng as i come from medical background and not eating in the morning puts your body in catabolic state..body comes on reserve mode… its my 2nd wk and i dont see any changes… DONT BUY IT UNLESS UR SOME FILTHY RICH GUY

The Bottom Line – Does Growth Factor-9 Work?
Are you sitting on the edge of your seat yet? Our interest in Growth Factor 9 leads us to a solid conclusion. We like that it contains a few natural ingredients and that we found reports of positive results. But, we don’t feel completely comfortable recommending the product because there are far too many negative reviews. Fasting appears to increase human growth hormone better than the supplement.
If it’s time to boost testosterone levels, our suggestion is to go with a supplement with a clinically-tested ingredient list. Check for no harmful side effects and a price that’s easy on your bank account.
Among the best products we’ve seen this year is one called Boost. The formula combines nine ingredients; clinically-tested with results often found in journals such as The Aging Male. Users tell us they see great results.
Plus, they’re so confident that you’ll love the supplement that they’re offering a 120-day money-back guarantee and 2-Week Sample.Learn More About Boost »
