Growth Factor 9 Review | Top Testosterone Supplements

Growth Factor 9 Review

Growth Factor 9 is an immensely popular muscle growth supplement with potential testosterone and HGH boosting capabilities. Since the beginning of 2018, there have been about 50 new testosterone and/or HGH boosters released, and many of them approach muscle growth and hormone boosting with super exciting new supplement technology. Read this Growth Factor 9 review to learn why we do NOT recommend it as one of our  Top 5 Testosterone Booster Supplements.

The Benefits of Growth Factor 9

Here are the claimed benefits of supplementing with Growth Factor 9…

  • Increases lean muscle mass
  • Reduces body fat
  • Boosts energy levels
  • Improves muscle recovery time
  • Elevates endurance levels

What Is Growth Factor 9?

The primary focus of Growth Factor 9 is to help the user build muscle and improve performance in the gym. There are a lot of claims being made on the website, but we’re not so sure the product lives up to these claims…more on that later.

The main focus with this particular product seems to be on increasing the user’s HGH (human growth hormone) levels, which is something that many experts in the industry view as dangerous.

Natural testosterone boosters are entirely safe, but HGH boosters are viewed as riskier. While they can cause muscle growth, they can also lead to some potentially very serious side effects. We generally advise people to stick with testosterone boosters for muscle growth as testosterone is far and away your body’s most important anabolic hormone.

If its muscle you’re after, testosterone is what you want to focus on…NOT human growth hormone.

How Does Growth Factor 9 Work?

The website claims that if you take the product on an empty stomach, it can cause the pituitary gland to release HGH and allow the HGH to flow more optimally like it did when you were younger.

While that sounds really interesting, this is a claim that a lot of companies make, and more often than not, the product doesn’t live up to the claim.

HGH can be very difficult to get your body produce, but increasing testosterone production within the body is a much less complicated feat, and we’ve found testosterone to be far more beneficial anyway.

Growth Factor 9 Ingredients – What Makes It Work?

L Arginine HCL: Arginine is the industry’s most widely known and utilized nitric oxide booster. It’s excellent for improving blood flow and enhancing your performance during your workouts.

It’s never a bad thing to see that a muscle-building supplement includes L Arginine, but in this case, the dosage of the Arginine is hidden within a proprietary blend. Therefore, there’s no way for us to know whether or not they used a large enough dosage.

L-Lysine HCL: Lysine is a crucial amino acid that can encourage muscle growth and improve muscle recovery time, which makes it an excellent ingredient to supplement with before you hit the gym.

With that being said, we have the same problem here as we did with this product’s inclusion of Arginine. The dosage size is hidden by the proprietary blend, so we’re not sure if they included enough Lysine for you to experience true benefits.

L-Glutamine: Glutamine is used by bodybuilders everywhere to help prevent muscle fatigue and expedite the process of muscle growth. It’s an excellent amino acid with a very promising list of potential benefits.

Some studies have even shown that glutamine can help your muscles grow while you’re asleep if you take it before bed.

However, let us save you some time here…every ingredient this product includes is part of one big proprietary blend. Therefore, there’s no way to know the exact sizes of the dosages.

Perhaps even more importantly, the size of the blend is only 2,900 milligrams, which means there’s almost no way the dosages are large enough for each ingredient.

Growth Factor 9 Reviews From Users

Part of our vetting process involves examining reviews from consumers who have tested the product. This way, we can combine our label-based analysis of the supplement with the experience-based feedback of the product’s users. Let’s see what people are saying…

Unfortunately, there have only been three user reviews submitted on Amazon, but the products current average rating is 4 stars. That’s a pretty solid average, so it looks like people are liking the product, but there’s not a whole lot of feedback to go off of here since there are only 3 reviews.

The Growth Factor 9 reviews on Amazon are fairly encouraging, but the product has gotten some negative feedback outside of Amazon as well. All reviews considered, there wasn’t a whole lot for us to learn here other than the fact that people’s results with the product are very mixed.

The Pros of Growth Factor 9

  • Contains some excellent ingredients
  • Shows some potential for muscle growth promotion
  • Could boost nitric oxide levels

The Cons of Growth Factor 9

  • The formula is one giant proprietary blend
  • Ingredient dosages are likely small since the blend is only 2,900 MG per serving
  • It claims to boost HGH levels, which can be risky
  • There is no evidence that it boosts testosterone levels, which is much more important than HGH
  • Pretty expensive at $79.99 per bottle

Our Conclusion On Growth Factor 9

At the end of the day, we don’t believe Growth Factor 9 can live up to most of the claims being made on the website. We simply don’t see enough evidence in the formula. The fact that it uses a proprietary blend turns us off of this product, and the fact that the blend is so small at only 2,900 MG doesn’t help.

The bottom line is if you’re interested in building lots of muscle mass and reducing your body fat percentage, we’d recommend sticking to testosterone boosters. Testosterone is MUCH more beneficial than HGH. You can learn about our favorite testosterone boosters here: Top 5 Testosterone Booster Supplements.
