Growth Factor 9 Overview

HGH has for quite a few years now been thought of by many as a sort of “fountain of youth”.

Synthetic HGH in the form of injections was used by athletes to improve their performance.

It worked so well it was banned.

Now, if you have enough money, you can spend thousands of dollars a month for these injections to help you feel energized and alert, preserve lean muscle mass, perform better in all kinds of ways, and even smooth away lines and wrinkles on your face.

But most people don’t have that kind of money for this kind of luxury.

Enter HGH releasers, and in particular, Growth Factor 9.

The idea behind these supplements is that they encourage your body’s own natural production process for HGH to kick into high gear.

So, without injections of banned synthetic substances, you get the benefits of more HGH coursing through your system.

There is a lot of anecdotal evidence that Growth Factor 9 and others like it can work, but until now, there has been no scientific evidence at all.

Growth Factor 9 changes that by having undergone a clinical study that showed a 682% increase in HGH levels.

But, is this too good to be true?

Read on to find out whether Growth Factor 9 is the supplement you’ve been waiting for.

How Growth Factor 9 Works

growth factor 9 reviewGrowth Factor 9 is a daily supplement that you must take on an empty stomach.

This most likely means that you both take the 4 capsule dose first thing in the morning and wait 2 hours before eating breakfast, or you take it before bed, making sure that you haven’t eaten in the 2 hours prior.

It’s also important that you use Growth Factor 9 in conjunction with a healthy lifestyle for optimum results.

If you follow the protocol, the kinds of results you can expect are:

  • Greater endurance and stamina.

  • Increased lean muscle mass.

  • Faster recovery times after working out.

  • Deeper, more restful sleep.

  • Elevated mood

What Do The Reviews Say?

Looking around on sites like and Vitamin Shoppe, you get a sense that Growth Factor 9 REALLY does have some potential.

The average star rating on is 7.2 out of 10 stars, which is NOT terrible.

Reading through some of these reviews makes me wonder if it’s right for everyone.

Most say it does a pretty good job at helping speed up recovery, but some people are literally calling it a “complete waste of money”.

Others are calling it the best supplement that they’ve ever taken.

Growth Factor 9 Ingredients

Growth Factor 9 is primarily made up of amino acids which when used in this combination are a precursor to HGH, thereby stimulating the pituitary gland to release more HGH than it would on its own.

The actual ingredients are:

  • L-Argnine HCI
  • L-Lysine HCI
  • N-Acetyl L-Cystein
  • L-Glutamine
  • Oxo-Proline
  • Schizonepeta Powder

A double-blind placebo controlled test was performed on Growth Factor 9. The information given about the test is a little brief, but from what I can gather, it included adult participants of all ages and both sexes, and the results were that 120 minutes after taking Growth Factor 9, HGH levels in blood had risen by 682%.

One thing that you do want to take into account however with this product is that you can purchase the first four ingredients all on your own as individual products.

So for the higher price point that this product sells for, you are primarily paying for Oxo-Proline and Schizonepeta powder, both of which don’t hold extremely powerful scientific research behind them and don’t appear to provide worthwhile effects.

The other ingredients however, do hold some promise.

L-Arginine is an amino acid that will help to boost the level of nitric oxide production in the body, which can help to increase blood flow and boost your workout performance.

It can also when the right conditions are provided, help to increase the HGH release by reducing the production of a substance called somatostatin, which inhibits growth hormone.

Studies are mixed however on the HGH boosting abilities of this amino acid, with some saying it actually does the opposite.

Still, you will find it in many products, such as HGH stacks, pre-workout products, as well as sold on its own.

L-Glutamine is another amino acid that’s quite well documented and can help assist with improving your immune function.

This then means enhanced cell repair and recovery, allowing you to get back into the gym to train again.

With ongoing high intensity training, your L-glutamine levels will drop, so adding this supplement can prove of benefit.

Once again however, you can purchase it all on its own for a very cost effective price.

Finally, N-Acetyl L-Cysteine is another ingredient to take note of as it does prove beneficial, but unfortunately not in terms of boosting HGH.

Instead, it can help to reduce the level of oxidative damage that occurs during intense training, boosting your recovery ability.

So consider it – but don’t think it’s going to work HGH boosting miracles.

So for those who are on a budget, you may be able to see similar results if you purchase the first four supplements individually and just stack them with each other.

Unfortunately as no dosage information has been listed on Growth Factor-9, but rather, it’s listed as a proprietary blend, this makes it hard to know precisely how much of each of those ingredients to take.

Growth Factor 9 Pros and Cons

Advantages of Growth Factor 9

  • It’s been clinically tested.

  • The retailer sites are loaded with favorable Growth Factor 9 reviews
  • It doesn’t involve injections or synthetic anything.

  • Some users who experience joint pain may find that subside while using Growth Factor 9
  • Appears to work especially well for men over 50 to regain energy they previous had from reading through customer reviews
  • Some users report their skin looks healthier and younger than it has in years.

  • May assist with improving sleep quality and/or duration.

  • Most individuals report no serious side effects from using this product.

Disadvantages of Growth Factor 9

  • It’s expensive (though not as expensive as injections).

  • There are plenty of negative Growth Factor 9 reviews from customers who state that it had no effect.

  • Even for those who do see results, in some cases it can take quite a few months of consistently using the product to see results from it.

  • Some users report it can make them feel more aggressive and angry
  • If you take these pills in the morning, you are advised to not eat for two hours following that, which can be problematic for many who need a good breakfast meal.

  • This product does not have a medical endorsement, so you cannot be 100% sure of its safety

Stacking Growth Factor 9 With Other Products

Because of the fact this product is quite unique in that it primarily targets only increased growth hormone levels, this allows you to stack it quite readily with any other product you wish.

Protein powder, pre workout products, post workout products, and most testosterone boosters will all be fine paired with Growth Factor-9.

The only other products you may wish to not pair with it include others designed to also increase growth hormone.

As this is a powerful product to start with, you should not have to worry about stacking it with any other product with the same goal.

Comparing Growth Factor 9 With Other HGH Supplements

Speaking of other HGH supplements, how does Growth Factor 9 compare?

Questions should be raised as to how much more powerful it is compared to more basic growth hormone booster products.

Chances are it is more powerful due to the addition of Oxo-Proline and Schizonepeta powder, however you will have to decide whether it’s worth justifying the increased cost.

It would seem this product is very powerful with the 682% increase it totes, however take note that that study is not actually referenced, so we aren’t quite sure if it really exists.

This in itself is questionable.

One additional thing to note is that this product does have a relatively shorter ingredient line-up list compared to some other products on the market, but don’t let that fool you.

Very often those with long ingredient lists simply contain more fillers and less active ingredients, so this often isn’t a good thing.

There’s definitely no question that this product has numerous positive reviews from those who have seen results with it, but with the price tag it comes with and the fact you may need to use it for multiple months to start seeing benefits, you’ll need to think hard about whether it’s an investment you’re willing to make.

Growth Factor 9 Compared To Other Testosterone Boosters

Another question you might be wondering about is are you better going with a growth hormone product like Growth Factor 9 or opting for a pure testosterone booster.

While both have the same objective – to help you gain lean muscle mass and boost your strength, keep in mind that Growth Factor 9 will cater more towards aging men who are also trying to slow down the process of aging and won’t have as strong libido boosting effects.

You should still notice some benefits, but they won’t be quite as noticeable as what you’d experience using a testosterone booster.

How Should I Take Growth Factor 9?

Finally, one last thing that was noted earlier is that you are instructed to take Growth Factor 9 first thing in the morning upon waking on an empty stomach.

Then you are supposed to not eat for 2 hours following until you then have your breakfast meal.

First, this is problematic because you will have the greatest natural growth hormone release when you first go to bed, not first thing in the morning.

So this product is not capitalizing on that.

Second, waiting 2 hours to eat upon waking is a great way to potentially put your body in a catabolic state, moving you away from your goals, not closer.

Especially if you are planning a morning or lunch workout, skipping breakfast like this would be completely unadvised.

Your body needs fuel upon waking, so by using this product, you’re robbing it of vital nutrients.

All the potential ‘good’ this product does is then offset by the harm you do from not eating.

So for this reason, you may want to reconsider utilizing this product.

Where to Buy Growth Factor 9

You can purchase Growth Factor 9 at GNC or online. The 120-count bottle retails for $99.99 and will last 30 days if used as directed.

You can find it a little cheaper, so make sure you look around.

Also note that some stores do state that it’s not available to Canadians, however if you live in Canada, you can find it on other websites to be shipped to your area.


It’s encouraging to see that the research is beginning to take place regarding how well HGH releasers do or do not work.

However, I’m a little skeptical about this study because while they do give some information about it, they don’t cite the actual study, and I haven’t been able to find it referred to anywhere else.

Something like this, if it were legitimate, would be big news, I would think.

I have been taking this product for about 1 week.Already I have noticed a gain in focus and recover time.

I take two in the morning when I wake up two hours before breakfast and two after my last meal before bed.I have also noticed a slight gain in strength and in stamina.

But yet again this isn't a magic pill you can't take it and sit around and wait for it to work.You'll just waste your money.

Nothing is going to happen unless you put in the work.In the gym and on the diet.

Anyone can work out for an hour a day it's what you put into your body the other 23 hours of the day.

I have been using Growth Factor 9 for about 2 months. I have tried most test boosters on the market but with GF-9 I really see results in the form of solid muscle mass gains, especially in my biceps and triceps, lower body has gained mass too.

I have been taking Growth Factor 9 for about three months. I take it right before I go to bed around 10:30 PM.

I sleep very deep and it has increased my muscle mass tremendously.My 15 1/2 biceps quickly grew to 16 1/2 inches! I'm impressed.

I have been in and out of the gym many times in my life and I have tried plenty of supplements along the way.

This was the first supplement that I took that I believed gave me good results.I've had huge gains in the first three months.

My husband actually pulled me aside and asked me if I was using steroids! It seems silly but we actually had that conversation... I'm very pleased with the results, and of course individual results may very.People I know tried things and they worked for them but not me.

You have to find what your body responds to, it's that simple.

Bonus - My sex drive increased drastically!

I'm not aware of this being a common side effect, but it's certainly possible that you're having a reaction to something in the supplement.  Take half a dose tomorrow at the same time and see if anything changes.- Rob

Should I work out directly after taking my 4 pills? Also, after taking my 4 pills can i drink my N.O. Xplode drink and then work out? -

Since you work out in the morning, you'd be better off taking your pills before bed, which is the alternate dosing recommendation on the package. Just make sure to wait 2 hours after you eat so you're taking your pills on an empty stomach.- Rob

I haven't used it myself, but the ingredient profile is decent and there are plenty of favorable customer reviews.  I haven't seen anything about a 3 year guarantee. In fact, on the Novex Biotech website, they mention a 30 day guarantee.- Rob
