Many men are searching for the best testosterone booster. We looked deep into Growth Factor-9, focusing on the ingredients, side effects, clinical research and customer service. We read hundreds of user comments and reviews. Then, we condensed and refined to give you the info you need.
What is Growth Factor-9?
First off, Growth Factor-9 is a natural growth hormone booster. It contains l-lysine HCL, l-arginine HCL, oxo-proline, n-acetyl l-cysteine, l-glutamine and Schizonepeta powder. You take four capsules as two, twice daily and the formula is supposed to help you “unleash your total performance.” The bottle is small enough to travel with, one benefit.
The product, formulated by Novex Biotech sometime after 2005, no longer appears on the official website. It looks like GH Regulator has replaced this formula. We like that the business has been around for more than 10 years and the BBB rating is good, but read on…
No One’s Getting Results – “A Problem?”
The first problem users have pertains to the effectiveness of Growth Factor-9 ingredients. Many people using the product just don’t see any results. “The competition in the supplement market is strong right now,” says our Research Editor. “If you can’t provide a formula that works, you’ll lose your spot on the shelf real quick.”
“I’ve taken the product for almost 30 days. 4 capsules per day as recommended. I’ve not notice any improvement in are area of my daily regimen. I push myself very hard and it may be that the product isn’t for someone who is an advanced athlete,” says a user.
“I purchased two bottle of GF-9 and consumed according to instructions. I did not feel any difference after two months,” offers another.
On the flip side, there are users who saw results.
One said, “Had a sore shoulder for months that kept me from lifting heavy. I stacked this with Testrovax and the soreness went away.”
As another put it, “There is a…(positive) difference in my energy levels, my ability to exercise, and my ability to recover.”
Side Effects – “I Don’t Feel So Good”
Growth Factor-9 side effects are an issue that comes up in more than a few reviews. “I have been taking this for 3 weeks, I have gained 4 pounds. I believe it is water which makes me wonder why I would be retaining so much water,” one user explains.
“I have been taking this product for over a week now and have experienced fatigue and brain fog like never before,” says another.
Some simply took the side effects and turned them into a benefit or experienced none at all.
“It did give me some anger issues, but channeling it to my workouts has increased my bench,” shared one user.
A customer claimed, “I can say that I didn’t experience the sleeplessness some have complained about.”
Based on our research, a supplement only needs one issue, like no changes to strength or muscle size, to ruin the chances of long-term success. If Growth Factor-9 results are not what the user expects them to be, the product doesn’t have long in this business.
Is There Verifiable Science?
Hidden in the product description of Growth Factor-9 is mention of a study. According to the information, the supplement can increase human growth hormone levels by more than 650%. There is no link to the published paper, but we did find even better information. The Journal of Clinical Investigation reports a “threefold increase in total GH secretion” within the first 24 hours with intermittent fasting. This method is free and clearly proven to work. At DietSpotlight, we’re looking for proof. If there’s none to be had, there’s no reason to stick around.
The Bottom Line – Does Growth Factor-9 Work?
Are you sitting on the edge of your seat yet? Our interest in Growth Factor 9 leads us to a solid conclusion. We like that all ingredients are listed online and there are some reports of positive results. But, we don’t feel completely comfortable recommending the product because there are far too many negative reviews. Fasting appears to increase human growth hormone better than the supplement.
If it’s time to boost testosterone levels, our suggestion is to go with a supplement with a clinically-tested ingredient list. Check for no harmful side effects and a price that’s easy on your bank account.
Among the best products we’ve seen in 2016 is one called Pronabolin. The formula combines nine clinically researched ingredients packed into a proprietary blend. It has been shown support energy and naturally boost testosterone levels. We found no mention of harmful side effects like those that come with prescription options. But, users are surely talking about the great results they’re seeing.
Plus, the makers of Pronabolin are so confident in their product they’re offering every customer a 120-day money-back guarantee and multiple-bottle discounts.
