3.7/5 - (3 votes)

In this GF 9 review, you will learn what Growth Factor 9 is, how does it work, its pros and cons, customer GF 9 reviews, and our opinion about this product.

Human growth hormone has been considered by many as a fountain of youth. However, as you get older, your hormone level starts declining, and you start showing symptoms of aging like wrinkles, under-eye bags, and reduced stamina.

So—It sounds great that the use of external synthetic growth hormone can improve athletic performance, but it’s not all roses and rainbows for those seeking to enhance their appearance or performance with HGH.

The media also portrays synthetic HGH in injections as glamorous; however, this type of treatment is banned due to its safety concerns from World Anti-Doping Agency. Because they found athletes are using these treatments extensively during competition periods without being subject to any medical oversight.

For that reason, many companies are now trying to safely boost your HGH level by using natural remedies and supplements. One such product is GF9—a blend of some amino acids and herbal ingredients that claim to improve your HGH level naturally.


The question is, do these supplements work the way they are advertised or are they doing some marketing tricks? Let’s find out what the reality is?

Let’s come to the main topic. First, a quick overview;

What is GF-9 (Growth Factor 9)

Growth Factor 9, also called GF-9, is a growth hormone supplement manufactured by the US-based nutrition brand Novex Biotech.

The product is packed with a mixture of different amino acids like L-lysine hydrochloride, L-arginine hydrochloride, and oxo-proline N-acetyl L-cysteine L-glutamine, and schizonepeta (aerial parts) powder.

GF 9 increases a peptide that supports recovery and endurance, improves sleep, increases energy, enhances libido, physical performance, muscle mass, and reduces body fats.

It has been clinically proven that GF-9 enhances the production of a potent single-chain peptide naturally linked to lean muscle stimulation.

This peptide’s optimal level is associated with lean muscle mass, reducing body fat, strengthening bones and joints, faster health, and better sleep.

Like Serovital, GF-9 is also aimed at people who believe they have no growth hormone and want to increase muscle mass and reduce their body fat percentage.

The product itself is a natural complex of amino acids and an herbal extract called Schizonpeta powder. According to a clinical trial, L-lysine-HCl, L-arginine-HCL, oxo-proline, N-acetyl-L-cysteine, and L-glutamine are complex Schizonepeta increased the HGH level by 628%.

A single growth factor (GF9) bottle containing 120 capsules can cost up to $ 99.00. You will need to take four capsules per day, which will last approximately 30 days. It is available on the official Growth Factor 9 website and Amazon.

So—at this price, GF 9 is surely not a cheap product, so does GF9 work, and is it worth it? Let’s find out more in this GF9 Supplement Review.

How does GF 9 work?

The use of this product may help people fight the effects of aging. With its proprietary blend and natural ingredients, it can counteract skin-aging problems such as wrinkles and sag. In addition, the product contains some amino acids and other herbal ingredients that the company claims to naturally raise your HGH level, improve your muscle tone, and increase stamina.

Does GF 9 Work?

GF-9 is considered safe for almost anyone to use due to its makeup of commonly consumed amino acids. However, while there are limited findings on the effectiveness of GF-9 in achieving HGH elevating purposes, it does not reliably work, and there is no evidence that they can raise GH over an extended period.

So—the bottom line on the safety and efficacy can be said with certainty: it’s safe for almost anyone to use due to its makeup of commonly consumed amino acids. But to see whether it work or not, you should either use it or check the authentic research behind each ingredient present in this formulation.

GF 9 Ingredients

The manufacturer claims that this product contains the mentioned ingredients to look at some of these ingredients’ proven benefits.

  • Gamma-Aminobutyric Acid (GABA)—3000mg: GABA is an effective supplement that boosts growth hormone levels. It induces deep sleep, and several bodybuilders vouch for its workout recovery benefits, but it could use more clinical evidence about muscle-building effects.
  • L-lysine hydrochloride: The most common use of L-lysine HCL in dietary supplementation is to aid with sores’ natural recovery. It may also help to manage stress in women and anxiety in males [1]. Some studies show that L-lysine daily doses for two months can help support the body’s ability to maintain a healthy blood sugar level.
  • L-arginine: L-arginine is an amino acid with two main functions: It helps produce proteins and produces gaseous nitric oxide (NO) in the body. Nitric oxide is essential for erectile function because it helps relax blood vessels to flow more oxygen-rich blood through the arteries. Healthy blood flow to the arteries of the penis is vital for normal erectile function.
  • N-acetyl L-cysteine: This is a semi amino acid used in different conditions like immune health and cellular damage; it also helps relieve Respiratory Conditions symptoms. It may also improve fertility in men and women.
  • L-glutamine: it is a type of glutamine found in food, supplements, and the human body. It is part of the proteins in your body and helps improve immune function and intestinal health.
  • Schizonepeta is a traditional Asian remedy for the common cold, head cold, and allergic skin eruptions. This herb has been shown to exhibit anti-inflammatory, antioxidant, and immunomodulatory activities.

What do I think about this product?

After reading the above GF 9 reviews and researching the company profile, it is clear this product could potentially be useful for some people, especially for improving athletic performance.

Some studies also suggest that the L-lysine in this formula would improve calcium absorption and relieve anxiety.

The two core ingredients in GF9 are L arginine and L lysine. According to another study, if you combine these two constituents sufficiently, your growth hormones will increase when you are in a resting position.

The company also shows clinical trial results to its users, and as per this trial, The company claims that this product will boost your HGH levels by 682%.

The Pennington Biomedical Research Center conducted this clinical study. According to this study, a combination of L-lysine HCl, L-arginine HCL, N-acetyl-l-cysteine, Oxo-proline, L-glutamine, and Schizonepeta increased HGH levels by 628%.

However, As a pharmacist, I am not fully convinced of this study, and there are a few reasons why I think this supplement will not help you increase your growth hormone.

  • Reason #1: The study is not peer-reviewed and is not recognized by the FDA.
  • Reason#2: Also, this is a small study that only involves 16 individuals.
  • Reason#3: The last and most important thing is that the results were concluded based on their thyroid function. The trial didn’t involve direct testing of the participants.

The ingredients in this supplement are a mix of amino acids and are all safe to use, provided you do not exceed the dose from the daily recommended intake.

So, If it’s safe and you can afford it, I suggest you give it a try or another high-quality alternative of GF 9.

If you have already decided to buy an HGH product, I recommend GenF20 Plus.

Why do I recommend it?

This company offers a 67 days money-back guarantee that says in volume about the manufacturer’s trust in its supplement.

The second thing is that It’s the #1 rated doctor endorsed HGH supplement in this category.

It comes with an alpha GPC oral spray that contains different amino acids and herbal extract important for the HGH release.

The GenF20 uses an enteric coating in its capsules for better absorption. Absorption plays a crucial role in the effectiveness of any supplement.

You can buy this product if you agree with our recommendation, and if you disagree, it’s fine and up to you. In that case, you can buy GF 9 or any other GF 9 alternatives.

Verdict- GF9 Reviews

If you are looking for a supplement that can boost your athletic performance, immunity, and better sleep, GF9 may be the best supplement for you.

But a proprietary blend of 2.9 grams is not the best way for a company to be transparent about its ingredients because it prevents consumers from independently verifying dosages.

Looking at the clinical trial results and manufacturer claims, you will see that the growth factor9 is not a bad product to try. At the same time, the supplement is safe to use with few side effects. 

However, if you look at some of the customer’s GF9 reviews, you will see a mix of some positive and negative testimonials. For some users, the formula increases the HGH, while this didn’t work for others.
