GF-9 review

Novex Biotech released GF9, which may increase growth hormone (GH) levels by up to 682%, which may seem unlikely to most users.

I have discussed this in detail after analyzing GF9 facts to help you know whether there’s research backing this level of GH increase from taking GF9.

In this GF9 review, I will discuss the working mechanism, studies backing GF9 claims, and the product formulation.

I have also discussed the medical studies on some GF9 ingredients to make you understand whether they can help you achieve such a massive increase in GH levels through regular GF9 use.

What is a GF-9 By Novex Biotech?

According to the maker’s claims, GF-9 stimulates natural HGH synthesis and offers potential benefits such as increased lean muscle mass and improved sleep.

However, it is essential to note that GF-9 does not contain actual growth hormone and is not examined for its effectiveness quality by regulatory bodies.

HGH anabolic hormone works to trigger fat metabolism. GF9 makers claim it can help provide similar benefits like increased lean muscle mass, increased energy levels, better mood, and stronger bone.

The official Novex Biotech website mentions limited evidence and claims GF9 benefits that are only possible through genuine HGH therapy alone.

GF-9 Ingredients

According to the official website, GF9 has amino acids and a plant extract. The maker mentions that GF9 has 2.9g or Genys Factor Proprietary Blend.

The study on the effectiveness of Growth Factor-9 (GF-9) raises questions about the precise amounts of each active ingredient in the formulation due to the manufacturer’s proprietary blend.

GF-9 has l-arginine, which has been found to induce small peaks in growth hormone (GH) synthesis when administered orally. However, studies investigating its effects on GH levels have yielded mixed results.

L-lysine amino acid in GF-9 does not appear to affect natural GH synthesis when tested in combination with l-arginine

One study has shown that oral administration of L-glutamine can temporarily increase GH synthesis. However, more research is needed to fully understand its impact on GH levels and whether this effect helps users.

It is important to note that while these ingredients may have some potential for affecting GH levels, their effectiveness and safety within the context of GF-9 remain uncertain due to limited scientific evidence and lack of transparency regarding their specific amounts in the formulation.

  • L-lysine

    L-lysine is known as the protein’s building block. It is required for growth and development of the body. It is an amino acid known to increase resting human growth hormone responses. However, a study found that L-lysine L-arginine did not stimulate GH levels and cannot be considered a s practical means of increasing human growth hormones in the body.

  • L-arginine

    Scientific studies examining the effects of oral L-arginine on HGH synthesis have yielded mixed results. Some studies suggest that it may induce small peaks in HGH levels, while others fail to demonstrate any significant impact.

    The optimal dosage and timing for oral L-arginine supplementation must be determined to stimulate HGH production effectively. Further research must determine the appropriate dosing regimen for maximizing its benefits.

  • Oxo-proline

    Oxo-proline, or pyroglutamic acid, is found in GF-9, a naturally occurring amino acid derivative essential in various physiological processes within the body.

    One study on individuals found that oxo-proline increased HGH levels compared to a placebo group. However, it should be noted that this study had a small sample size and has yet to be replicated.

    It is essential to recognize that the overall effectiveness and safety of oxo-proline as an HGH booster still need to be determined due to the lack of comprehensive scientific evidence. Additionally, oxo-proline’s specific dosage and long-term effects in GF9 remain unknown.

  • Fermented L-cysteine

    Fermented L-cysteine, another ingredient found in the GF-9, may potentially impact human growth hormone (HGH) levels. However, it is essential to note that the evidence supporting this claim must be revised, and extensive studies are required to draw definitive conclusions.

    To provide a comprehensive understanding of fermented L-cysteine concerning HGH levels and its safety, the following points should be considered:

    The potential impact of fermented L-cysteine on HGH levels is based on limited scientific studies. These studies have shown mixed results and a lack of replication, making it difficult to establish a clear cause-and-effect relationship between fermented L-cysteine and HGH synthesis.

    The manufacturer does not disclose the exact amount of fermented L-cysteine present in the GF-9, which makes it difficult to assess its potential efficacy in stimulating HGH levels.

  • L-glutamine

    Limited scientific research suggests that oral L-glutamine may transiently affect growth hormone synthesis, as evidenced by a study showing a temporary increase in levels 30 minutes after administration.

    The current scientific research regarding the impact of L-glutamine on growth hormone synthesis is limited.

    It should also be mentioned that the effects of L-glutamine on growth hormone synthesis quickly dissipated within the first hour after administration. This indicates that any potential increase in growth hormone levels induced by L-glutamine will likely be short-lived.

  • Schizonepeta Powder

    Schizonepeta has been traditionally used in Chinese medicine to treat colds, allergies, and inflammation. It contains anti-inflammatory and anti-immunomodulatory effects. However, there is a need for more scientific studies investigating the direct impact of Schizonepeta on HGH levels or its ability to stimulate HGH production.

    Without clinical trials supporting its claims, whether Schizonepeta contributes significantly to GF-9’s proposed benefits related to HGH synthesis remains uncertain.

    While Schizonepeta powder may have potential health benefits beyond HGH stimulation, it does not possess substantial scientific evidence directly linking it to increased HGH levels or improved growth hormone deficiency symptoms.

Is GF-9 safe?

The safety and effectiveness of the GF-9 supplement have yet to be established due to a lack of rigorous scientific research and regulatory oversight.

GF9 is not subject to control by any regulatory institutions, it is not third-party tested, and the manufacturer does not disclose the exact doses of each ingredient in its proprietary blend.

While the amino acids listed on the label are generally safe and found naturally in the human diet, there are concerns about one ingredient called Schizonepeta. According to medical resources, specific doses of Schizonepeta may potentially damage the liver.

Limited information is available regarding possible side effects associated with GF-9. The manufacturer has not provided any data on adverse reactions or warnings related to its use.

Issues With GF9

GF-9 claims to stimulate natural HGH synthesis, presenting several issues individuals should consider while seeking safe and effective options.

It is important to note that GF-9 does not contain actual growth hormone and lacks FDA approval. The manufacturer’s claims of increased lean muscle mass and improved sleep are supported by limited evidence.

The study has set up flaws with a small sample size, increasing the risk of bias. Additionally, participants in the study were healthy individuals in a fasted state, which can naturally lead to increased GH levels. This study, however, fails to consider the subsequent rapid drop in GH levels after a spike.

While GF-9 makers mention it contains amino acids and one plant extract in its proprietary blend, they kept it undisclosed, the exact amount of each active ingredient included in the formulation.

Although L-arginine may induce small peaks in HGH synthesis when administered orally, mixed results have been observed regarding its effectiveness.

G9 has L-lysine, which does not appear to affect natural HGH synthesis when tested with L-arginine. Only one study has shown a temporary increase in growth hormone synthesis with oral L-glutamine.

Consulting with healthcare professionals is strongly advised due to the potential risks associated with unregulated products like GF-9.

GF9 Alternatives

A natural and safer alternative to the GF-9 is HGH-X2 by CrazyBulk. It claims to boost lean mass and development. HGH-X2 contains a blend of amino acids, herbs, and plant extracts that are specifically formulated to support muscle development. These ingredients work synergistically to stimulate growth hormone production, increasing lean muscle mass. HGH-2 Somatropin claims to work by stimulating the pituitary gland to release more HGH hormone into the blood.

According to CrazyBulk, the HGH-X2 formulation also includes components that promote faster recovery after intense workouts. This can help reduce muscle soreness and fatigue, allowing you to train more frequently and effectively.

A regular dosage of HGH-X2 may help you experience an increase in energy levels, which can optimize your athletic performance and help you maintain an active lifestyle.
