Are there any Growth Factor 9 alternatives?

There are many alternatives to Growth Factor 9 available. One popular option is ‘HGF Max’.


Human growth hormone (HGH) is a hormone naturally produced within the pituitary gland in our brains.

It is crucial for cell regeneration, reproductive health, strength, growth and health of our body as well as other important biological functions.

Unfortunately, with age HGH levels start to take a nosedive resulting in unpleasant symptoms.

Growth Factor 9 uses a combination of amino acids and natural extracts to boost HGH levels and restore strength and vitality.

It claims users will see the following benefits:

Increase Muscle Mass

As we age, one of the first things many of us notice is that it becomes harder to stay as chiselled and toned as when we were younger.

One of the reasons for this will be the decline in human growth hormone (HGH) which takes place with age. (1)

HGH is well known for its ability to increase muscle mass and strength in those who use it as a supplement. (2)

In one study, men between the ages of 50 and 70 years old were administered HGH over 6 months. They experienced an increase in lower body muscle strength compared to those in the placebo group. (3)

Growth Factor 9 can help you to regain the strength and muscle of your youth by using a blend of ingredients which claim to boost HGH production.

Improve Energy Levels

A reduction in HGH can affect the amount of energy you have at your disposal. This can have a negative effect upon your day to day life, as well as during exercise. (4)

By increasing HGH levels, Growth Factor 9 can return the spring to your step and the power in your stride.

Human growth hormone can enhance the efficiency of the cardiovascular system and increase the supply of oxygenated blood. (5,6)

This improvement in heart and lung function serves to elevate energy and stamina.

Increased Exercise Performance

It is not unusual for people to experience tiredness and a drop in physical stamina from middle age onwards.

This can have many causes, but one of the most important is due to less HGH in the body.

HGH is connected to physical performance and reduced fatigue. (7,8)

By elevating HGH levels, Growth Factor 9 can improve your performance in the gym  and leave you feeling more energised afterwards. .

Improved Recovery Times

As we age our ability to recover from stresses and strains diminishes.

Whereas years ago a long day on your feet or a hard gym session would be easily forgotten, now the aches and tiredness linger longer than you would like.

One of the key factors in our ability to repair and rejuvenate after exercise is the amount of HGH we have in our body.

Growth Factor 9 can boost your recovery times and get you back in the gym faster.

HGH is required for the rapid restoration after stress has been placed upon our muscles and tissues.

It serves to stimulate the production of collagen, aiding the repair process. (9)


Growth Factor 9 uses the following blend of amino acids and extracts:


L-glutamine is a very common amino acid which is found in great quantities in the human body.

It is a popular supplement for weight lifters as it is known to improve exercise performance.

When you train hard in the gym, the levels of l-glutamine become depleted. This has a negative effect upon performance, strength and recovery. Taking l-glutamine after exercise can improve recovery times dramatically. (10)

L-glutamine supplementation has been proven to increase both strength and HGH levels. Additional HGH also boosts muscle growth. (11)

L-Lysine HCl

Due to the role it plays in the synthesis of antibodies, l-lysine is required for a healthy immune system.  These are a crucial aspect in the response to infection. (12)

Clinical studies have shown that l-lysine also bolsters the effectiveness of l-arginine. When used in combination they can effectively stimulate an increase in levels of HGH more so than what they would alone. (13)

Furthermore, l-lysine reduces stress and anxiety, helping you to focus on the task at hand. (14)


Oxoproline is a rather obscure ingredient of which there is has been very little research thus far.

It’s derived from glutamic acid which is a type of amino acid responsible for sending and receiving signals across the nervous system. (15)

However, we couldn’t find any evidence linking this ingredient to HGH.

L-Arginine HCI

L-arginine HCL stands for ‘l-arginine hydrochloride’.

This amino is often supplemented to improve performance during intense exercise. It can also counteract impotence, support a healthy immune system and protect heart health. (16)

The hydrochloride form of l-arginine is absorbed and used by the human body much better than other kinds. In other words, it has a higher ‘bioavailability’ than standard l-arginine.

L-arginine HCL has been shown in clinical trials to elevate nitric oxide levels within the muscles. This is important for muscle growth as it increases blood flow to the area and enables a stronger workout. (17,18)

L-arginine HCL doesn’t increase HGH directly, but is does act as a support. It blocks the action of a chemical called somatostatin which inhibits the secretion of HGH. (19,20)

Further studies have shown l-arginine supplementation increases HGH levels by as much as 100 percent. (21)

N-Acetyl L-Cysteine (NAC)

N-acetyl l-cysteine is another kind of amino acid believed to have beneficial properties.

It’s used as a treatment for many different medical conditions, from kidney problems to respiratory infections. (22)

NAC is known to positively increase the levels of a compound called ‘glutathione’. This chemical is essential for the health of the brain, lungs and liver among other benefits. (23)

Because of its relationship with glutathione, NAC has also been used as an effective treatment for male infertility. (24)

Schizonepeta Powder

Schizonepeta is a kind of herb often referred to by its other name, ‘japanese catnip’.

There is some clinical evidence that schizonepeta has anti inflammatory properties. (25)

Whilst it is difficult to find any direct scientific evidence it can raise HGH levels, there is a train of thought which ties HGH levels to inflammation.

It is believed cell inflammation can result in diminishing levels of HGH, therefore an anti inflammatory such as schizonepeta may prove beneficial in the preservation of said hormone levels. (26)

Side Effects

Possible side effects from high levels of HGH are: muscle pains, joint pains, swelling, numbness, tingling and high cholesterol.

L-arginine can cause diarrhea, blood test abnormalities, bloating, low blood pressure, stomach discomfort and respiratory discomfort.

N-acetyl l-cysteine can result in insomnia, chest tightness, swelling of the mouth, headaches, low blood pressure, vomiting, diarrhea, constipation and rashes.

As with any supplement, talk to a medical professional before use if you are pregnant, expecting surgery or on prescription medication.

If you feel unwell, stop use and speak to your physician.

Recommended Dosage

The recommended dosage of Growth Factor 9 is to take four capsules on an empty stomach. You can choose whether you take them two hours before breakfast or two hours after dinner.

The reason behind taking the capsules on a empty stomach is so that the amino acids in your food do not interfere with those included in the formula.


Growth factor 9 is a dietary supplement which uses a combination of amino acids and herbal extracts to boost human growth hormone levels.

Its formula promises to help you gain muscle, improve sex drive, increase energy and reduce recovery time.

We like how the formula is free from synthetics or artificial hormones which have the potential to do harm.

The vast majority of ingredients have scientific evidence supporting the fact they can elevate HGH levels in the body. However, it is unfortunate there are some which we couldn’t find any supportive studies for.

Overall, Growth Factor 9 does show potential as an effective supplement for those who are feeling their age, or simply just want an extra kick in the gym.
