GF 9 Review: Does Growth Factor 9 Work In 2024?

This comprehensive GF 9 review explores the efficacy of “GF9 (Growth Factor 9),” a natural human growth hormone supplement that enhances growth hormones and fosters healthy aging. We aim to provide honest insights to our readers by combining personal testing, research on its ingredients, direct customer feedback, and my expert opinion as a pharmacist. Let’s uncover the truth together.

Hailed as a “fountain of youth,” Human growth hormone (HGH) has long captivated many with its promises of vitality. However, as age catches up, our HGH levels decline, leading to visible signs of aging like wrinkles, under-eye bags, and diminished stamina.

To counter this, synthetic HGH injections have been popular among those seeking to boost their hormone levels and enhance athletic performance. However, the allure of these injections is met with safety concerns, resulting in their ban by the World Anti-Doping Agency. Athletes were found to exploit these treatments during competitions without proper medical oversight.

In light of this, companies are now exploring safer ways to elevate HGH levels using natural remedies and supplements. Enter Growth Factor 9 (GF9), a blend of amino acids and herbal ingredients that claim to improve HGH levels naturally.

But the real question remains: Does GF9 live up to its advertisements, or is it just another marketing gimmick? In this article, we embark on a journey to uncover the reality behind GF9’s efficacy and whether it’s genuinely worth the investment. Let’s dig deep and separate the facts from fiction surrounding this intriguing supplement.

About The Company

Novex Biotech is the company responsible for developing the GF9 supplement. Founded in 2005, this US-based company empowers men to optimize their health and well-being. Novex Biotech is renowned for producing top-notch supplements, including TestroVax, Oxydrene, GF9, and Pre7, ensuring that customers can achieve their health and vitality goals.

What is GF-9 (Growth Factor 9)?

Growth Factor 9, also called GF-9, is a growth hormone supplement packed with a mixture of different amino acids like L-lysine hydrochloride, L-arginine hydrochloride, oxo-proline N-acetyl L-cysteine, L-glutamine, and schizonepeta (aerial parts) powder.

These natural extracts and amino acids are said to increase a peptide that supports recovery and endurance, improves sleep, increases energy, enhances libido, physical performance, and muscle mass, and reduces body fats.

The manufacturer claims that it has been clinically proven to enhance 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, reduced body fat, strengthened bones and joints, faster health, and better sleep.

Like Serovital, GF-9 is also aimed at people who believe they have low growth hormone and want to increase muscle mass and reduce their body fat percentage.

The product is a natural complex of amino acids and an herbal extract called Schizonpeta powder, and according to a clinical trial, L-lysine-HCl, L-arginine-HCL, oxo-proline, N-acetyl-L-cysteine, L-glutamine, and complex Schizonepeta powder 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 daily, lasting approximately 30 days. It is available on the official Growth Factor 9 website and Amazon.

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

How does GF 9 work?

GF9 is designed to combat the effects of aging, offering a proprietary blend of natural ingredients that target skin-aging issues like wrinkles and sagging. The product aims to raise HGH (human growth hormone) levels, improving muscle tone and stamina.

Although the exact mechanism of how the amino acids in GF9 increase growth hormone levels is not fully understood, recent studies suggest that oral or parenteral intake of amino acids can enhance GH hormone release.

While GF9 may offer benefits, there are evidence-based methods to increase growth hormones naturally. Intermittent fasting, optimizing sleep, reducing body fat, and limiting sugar intake effectively boost HGH levels. Additionally, supplements like arginine and GABA can also aid in increasing HGH levels.

Overall, GF9 presents a potential option to counteract aging effects, but it’s also essential to consider these evidence-based approaches for natural HGH elevation.

Does GF 9 Work?

clinical study in the American Journal of Therapeutics explored GF9’s impact on growth hormone levels. The research was funded by the Sierra Research Group, a company sharing the same registered address as Novex Biotech. This connection raises concerns about potential bias.

The study did show that GF9 increased GH levels within 120 minutes. However, well-established research consistently demonstrates that amino acids can temporarily elevate GH levels. No conclusive evidence supports a lasting GH increase through amino acid supplementation. Novex Biotech’s website also mentions ongoing studies on long-term effects.

In summary, according to the clinical trial, GF9 likely provides a short-term GH boost, but the benefits of this temporary increase remain uncertain. We lack sufficient evidence to claim long-term GH-level enhancements.

In terms of safety, GF9 is considered safe for most individuals due to its use of commonly consumed amino acids. Consider using it or reviewing the research behind each ingredient in this formulation to determine its efficacy.

We also rely on feedback from verified customers to gauge its effectiveness. Of those who have used it, 59% have awarded it a 5-star rating, while 16% have given it 4/5 stars.

Based on verified customer reviews and limited research, we suggest trying GF9 or exploring high-quality alternatives like GenF20 Plus.

GF 9 Ingredients

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

  • 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 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. A research report published in the Journal of Applied Physiology discovered that taking l-arginine supplements caused a significant boost in GH (growth hormone) levels when the subjects were at rest, increasing them by approximately 100%. However, interestingly, this supplementation was found to lower GH levels compared to a placebo during exercise.
  • N-acetyl L-cysteine is a semi-amino acid used in conditions like immune health and cellular damage; it also helps relieve symptoms of respiratory conditions. It may also improve fertility in men and women.
  • L-glutamine is a 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.
  • Titanium dioxide: Inactive ingredients such as titanium dioxide are not allowed as food additives in the European Union.

Is There A Room For Improvement?

As a pharmacist, there is room for improvement in the GF9 supplement formulation to make it an ideal anti-aging supplement. While GF9 is already popular, I recommend adding clinically proven ingredients to enhance its effectiveness.

One essential ingredient to consider is Nicotinamide Mono Nucleotide (NMN), which has been shown to improve cellular and mitochondrial health, which can decline with age. Another critical ingredient is CoQ10, which has been found to reduce the risk of age-related diseases.

In addition, incorporating Curcumin into the supplement can provide natural anti-inflammatory benefits, which can be particularly helpful in mitigating the effects of aging.

Lastly, adding collagen to the formulation can aid in restoring skin health, which is an essential factor in anti-aging.

By including these proven ingredients, the GF9 supplement can become even more effective in promoting anti-aging benefits and supporting overall health and wellness.

What Our Tester (Nathan) Says About GF9?

Nathan, a 45-year-old male, volunteered to test GF9 and shared his experience after using the supplement for approximately eight weeks. He said the results were promising, as he noticed significant improvements in various aspects of his well-being.

Firstly, Nathan reported feeling more energized throughout the day, which enhanced his overall productivity and vitality. Secondly, he observed a remarkable improvement in his skin, with smoother texture and reduced signs of aging like wrinkles and sagging.

Additionally, Nathan was delighted that his stamina had increased, enabling him to engage in physical activities with greater endurance and enthusiasm. Furthermore, the supplement positively impacted his sleep cycle, leading to more restful and rejuvenating nights.

(Update: 17 January 2024) I asked Nathan again about the product and his feedback, and he was very impressed with the result and has been using it for over a year.

Overall, Nathan experienced a boost in his energy levels, contributing to an enhanced sense of well-being. His positive feedback aligns with the product’s claims, making GF9 a promising option for those seeking to address aging-related concerns and improve their health and vitality. 

What do I think about this product?

After reading the above GF 9 reviews, our tester feedback, and researching the company profile, it is clear this product could potentially be helpful 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 resting.

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 or recognized by the FDA.
  • Reason#2: This is a small study involving only 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 try it or another high-quality alternative to GF 9.

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

Why do I recommend GenF20 Plus?

This company offers a 67-day 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 extracts essential 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 okay and up to you. In that case, you can buy GF 9 or any other GF 9 alternatives.

Frequently Asked Questions (FAQs)

Question: How Effective is GF9 supplement?

GF-9 has recently been made more popular due to the research on its ability to increase growth hormone levels. While these results were undeniably positive, with the study showing a 682% increase, it is important to note that its competitor product, SeroVital, was used in this clinical trial, which could skew the results as different batches may be produced. GF9 is precisely identical to Serovital. There is still no conclusive evidence that GF-9 can effectively help with other issues beyond increasing growth hormone levels. However, more research must be conducted to fully understand and confirm this supplement’s potential.

Question: Is GF9 a steroid?

The answer is a definitive ‘no.’ GF9 is a natural supplement made from different amino acids and herbal extracts to help you achieve optimal physical performance. It can help you increase your energy levels and maximize physical output during weightlifting or high-intensity training activities. Because it is derived from natural ingredients, GF9 contains no synthetic compounds prohibited in most athletic fields. It is the perfect supplement for athletes who wish to stay within the competition rules.

Question: Is GF9 legit?

This is a very valid question indeed and one that is often asked. Thankfully, the answer is yes! GF9 is known to be made from natural ingredients, and the company responsible for producing this supplement has an excellent reputation for manufacturing well-trusted brands. Results can vary significantly per person, but rest assured that you are indeed purchasing a legitimate product.

Question: How do you use it—GF 9 Dosage?

The recommended intake is four capsules with water on an empty stomach, either in the morning two hours before breakfast or two hours after dinner before bedtime.

The best way to take Growth Factor 9 is by taking four capsules first thing in the morning on an empty stomach, waiting 2 hours before eating breakfast, or taking it at bedtime when not eating for two consecutive hours prior. This will provide you with optimal results.

  • Avoid over dosage
  • Don’t take it if you are under the age of 18.
  • Avoid or consult your physician if you are a pregnant or breastfeeding mom.

Question: Where To Buy GF9?

The best place to buy GF9 is from the company website, CVS pharmacy, Amazon, or Walmart.

Purchasing GF9 from the company website ensures you get the freshest and original product possible and access special offers and discounts.

On Amazon, customers can find a wide selection of GF9 products. They also offer competitive prices and free delivery on orders with certain spending thresholds.

Walmart also stocks GF9 in both physical stores and online. Customers can check store availability before purchasing or shopping online for convenience and competitive prices.

The 120-count bottle retails for $99.99 and will last 30 days if used as directed. Still, you should also be on the lookout for cheaper alternatives in your area because some stores state that they are unavailable to Canadians or other nationalities. In contrast, other sites offer a different location delivery service.

Question: What sets GF9 supplement apart from its competitors?

Novex Biotech’s men’s supplements are genuinely of the highest quality because they are made in GMP-certified facilities and are hormone-free and gluten-free. Their money-back guarantee, high quality, and proven ingredients set them apart from their competitors because you can take their lab-tested and safe product with complete confidence.

Furthermore, the product is formulated to naturally optimize pituitary functions related to physical performance, energy, drive, recovery, and sleep, making it an attractive choice for people looking for a comprehensive solution. The popularity of this supplement is illustrated by the 4.1/5 star ratings it has garnered on Amazon from over 1400 ratings.

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.

However, 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.

The clinical trial results and manufacturer claims show 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, looking at some of the customer reviews, you will see a mix of positive and negative testimonials. The formula increases the HGH for some users, while this doesn’t work for others.
