GenF20 Plus Review 2024: Benefits, Side Effects, & More

GenF20 Plus is one of a few HGH releasers that have been tested in clinical trials. This review provides you with everything you need to know about GenF20 Plus, including ingredients, bodybuilding benefits, and side effects.

GenF20 Plus is now one of the most efficient HGH supplements available.

It combines Eastern and Western medicine to create the ideal anti-aging HGH supplement.

Due to its all-natural formula, GenF20 is great for supporting the body's own HGH production.

This analysis provides the most comprehensive information about the health benefits of GenF20 Plus, so you can decide if it matches your goals.

What is GenF20 Plus?

GenF20 is a dietary supplement for bodybuilders and athletic enthusiasts designed to boost the natural production of the human growth hormone, or HGH.

HGH is a hormone produced by the pituitary gland, a master gland of the human body. The main function of HGH is to promote the growth and repair of cells and tissues.

HGH levels decrease significantly as we age, with a 50% drop every 7 years after the age of 18-21.⁽¹⁾ This results in fat gain, decreased muscle tone, low energy, anxiety, and decreased bone density.⁽²⁾

Due to its natural formula, GenF20 is a safe and legal alternative to synthetic HGH injections. GenF20 also has little to no side effects, in contrast to HGH injections that often come with side effects like muscle pain, joint pain, swelling, and numbness.

Here are the pros and cons of GenF20:

Pros

• Promotes lean muscle growth and muscle tone
• Enhances metabolism and helps improve healthier body composition
• Higher energy levels and libido
• Improves bone density
• Boosts athletic performance
• Improves sleep quality
• Affordable compared to other HGH products

Cons

• May cause nausea or stomach upset

What Are the Ingredients in GenF20 Plus?

Let's take a deeper look into the GenF20 Plus natural ingredients and their positive effects.

L-Arginine

L-arginine is an essential precursor for the synthesis of proteins and other important biological molecules. In combination with resistance and strength training, L-arginine stimulates muscle growth.⁽³⁾ Arginine has been shown to increase blood flow to the muscles.⁽⁴⁾ Arginine also improves the functioning of the cardiovascular, respiratory, immune, reproductive, and digestive systems,⁽⁵⁾ and lowers blood pressure.⁽⁶⁾

L-Glutamine

L-glutamine is one of the essential amino acids and the most abundant amino acid in the body.⁽⁷⁾ It plays an important role in the synthesis of glucose in the liver, protein synthesis, and the fueling of intestinal and immune cells.⁽⁸⁾ Glutamine also promotes muscle growth. Combined supplementation with L-glutamine and L-arginine significantly increases HGH levels.⁽⁹⁾

L-Glycine

L-glycine is a nonessential amino acid important for the synthesis of collagen, glucose, hemoglobin, and bile acids. Glycine stimulates HGH production.⁽¹⁰⁾ Glycine-arginine-α-ketoisocaproic acid (GAKIC) supplementation improves muscle performance and fatigue resistance.^{(11)(12) (13)}

L-Lysine

L-lysine is an essential amino acid that helps the body make proteins, including the proteins that make up muscles.⁽¹⁴⁾ One study has shown that lysine can boost HGH secretion when combined with L-arginine,⁽¹⁵⁾ although other studies have produced mixed results.⁽¹⁶⁾ Lysine deficiency, especially in athletes, leads to protein degradation, a slowdown of protein synthesis, and increased recovery time. Lysine also participates in the synthesis of collagen, calcium metabolism, and fatty acid metabolism.^{(17) (18)}

L-Tyrosine

L-tyrosine is required for the synthesis of proteins, enzymes, thyroid hormones, and the skin pigment melanin. It's thought that L-tyrosine boosts metabolism via stimulation of thyroid hormone synthesis, which subsequently promotes weight loss. It's also essential for the production of brain neurotransmitters, including dopamine, epinephrine, and norepinephrine.⁽¹⁹⁾

Astragalus Root Extract

Astragalus is a popular herb in traditional Chinese medicine. It supports immune health,⁽²⁰⁾ which may be valuable for athletes as repeated bouts of strenuous exercise negatively impact immune function.⁽²¹⁾ Astragalus restores immune balance and prevents immunosuppression in heavily-trained athletes.⁽²²⁾ Animal and experimental studies have also shown that astragalus improves the insulin sensitivity of muscles and increases the rate of glucose utilization by up to 25%.^(23)(24) In combination with other herbal ingredients, astragalus helps achieve a greater weekly resistance exercise workload.⁽²⁵⁾ Astragalus also improves cardiovascular health. It decreases blood pressure,⁽²⁶⁾ improves heart contractile capacity,⁽²⁷⁾ and prevents heart damage induced by overtraining.⁽²⁸⁾

Deer Antler Velvet

Deer antler velvet is a traditional Chinese medicine supplement, and preliminary evidence shows that it has the potential to improve physical performance,⁽²⁹⁾ but more research is needed.

GABA

Gamma-aminobutyric acid, or GABA, is the main inhibitory neurotransmitter in the central nervous system. There is strong evidence that GABA increases the production and release of HGH.^{(30) (31)}

Colostrum

Colostrum improves immune health^(32)(33) and helps maintain the integrity of the gastrointestinal lining, especially during strenuous exercise.^(34)(35) It can also increase muscle protein synthesis.⁽³⁶⁾ Colostrum may promote faster acute recovery, enhancing total power output on subsequent exercise bouts.⁽³⁷⁾

L-Valine

L-valine is one of the three branched-chain amino acids (BCAAs), alongside leucine and isoleucine. It helps prevent delayed-onset muscle soreness (DOMS) and muscle fatigue and is useful for muscle growth and exercise recovery.⁽³⁸⁾

Pituitary (Anterior)

Commonly known as the anterior pituitary powder, it is an extract of bovine pituitary glands, rich in hormones and growth factors.⁽³⁹⁾ It naturally boosts HGH production, aiding in muscle growth.

Phosphatidyl Choline

Phosphatidylcholine is a phospholipid that has recently been shown to improve exercise performance. Phosphatidylcholine counteracts the negative effects of increased cortisol levels and a drop in choline levels during intense exercise. It also leads to a faster drop in lactic acid levels during exercise and faster heart rate recovery during breaks.⁽⁴⁰⁾

L-Ornithine

One study found that supplementation of L-ornithine with L-arginine significantly increases growth hormone levels after heavy-resistance exercise in strength-trained athletes.⁽⁴¹⁾ In addition, ornithine and arginine serve as precursors of the amino acid proline, the key component of collagen, which helps in tissue repair. L-ornithine alone has also been shown to significantly increase HGH levels in the blood.⁽⁴²⁾

GTF Chromium

Also known as chromium polynicotinate, this is a popular dietary supplement for blood sugar regulation and weight loss support. A recent review showed that taking chromium supplements helps preserve lean body mass and makes it easier to lose fat.⁽⁴³⁾

Why Take an HGH Supplement?

Maintaining optimal HGH levels is critical for bodybuilders because HGH is the main hormone that promotes lean muscle growth. However, regular people can also benefit from HGH-boosting supplements due to the fact that HGH starts to decline after the age of about 21 years old. Growth hormone deficiency comes with many negative adverse effects, lowering the quality of life, as well as physical and mental performance. You also have low energy and don't feel refreshed after a night sleep.

Taking HGH supplements is also better than painful synthetic HGH injections. Instead of their nasty side effects, you get numerous health benefits that come with the natural ingredients in HGH supplements.

The key ingredients in HGH boosters are amino acids, herbal extracts, and sometimes vitamins and minerals.

Lastly, many HGH supplements provide anti-aging benefits, helping you successfully deal with age-related health issues.

How Does GenF20 Plus Product Work in the Body?

GenF20 Plus boosts natural HGH production. HGH itself can act directly on body cells and indirectly, through increased serum insulin-like growth factor 1 (IGF-1) levels, on physiological processes in the human body.

Higher HGH and serum IGF-1 levels promote muscle protein synthesis and speed up fat metabolism. Serum IGF-1 levels is a marker of HGH production: increased IGF-1 means HGH production is increased as well.

In fact, GenF20 is the only HGH releaser that has been studied in a clinical trial, in which serum IGF-1 levels increased by 28% in just 84 days of using the supplement. You can find out more about the study here. In addition, it's likely the only HGH releaser that has been recommended by medical doctor Steven Lamm, one of the top experts in men's health.

As a result, HGH promotes lean muscle mass gain and fat loss.

Higher HGH levels also lead to better mood and motivation, as well as improved cognitive function and performance.

What Are the Health Benefits of Using GenF20 Plus?

Due to the multiple effects of growth hormone in the human body, GenF20 provides you with numerous health benefits.

GenF20 improves skin health by improving the skin tone and elasticity while reducing fine lines and wrinkles. Amino acids also help to strengthen the nails and improve their appearance.

HGH is necessary for tissue regeneration and growth, which affects the look of your skin.

Higher HGH levels also prevent muscle breakdown, preserve lean muscle mass, and increase strength.

Depression is common in people with growth hormone deficiency, and supporting optimal HGH production may help with anxiety and depression.

Aging is often associated with a lack of energy, and declining HGH and testosterone are the first to be blamed. Helping your body naturally make more HGH and testosterone not only helps you build muscle, but it also gives you more energy.

Additional health benefits of taking GenF20 Plus include improved nerve function and enhanced nitric oxide production, which improves blood flow. In turn, enhanced nitric oxide production helps with erectile dysfunction.

Last but not least, the GenF20 Plus formula helps improve your cognitive function, so you feel more focused.
