What Is Nugenix?

Testosterone Booster is a testosterone enhancing compound most popular with bodybuilders, athletes and fitness buffs that use extra testosterone to help them bulk up, build muscle and strength as well as burn fat. This product is formulated to restore testosterone levels in men that may not be producing adequate amounts on their own, or for bodybuilders that have reached a plateau in size and want to increase their muscle mass and strength.

Manufacturer, Company, Brand

Direct Digital LLC is the primary developer and marketer of Nugenix, a brand new, all natural booster of testosterone by InstaFlex.


How It Works?

Testosterone Booster is a natural testosterone booster that helps men who are experiencing the gradual reduction in their levels of testosterone as they age. Starting at about age thirty, men start noticing a drop in their testosterone levels which only gets worse with every passing year. Testosterone booster works to restore testosterone levels in healthy men, and is one of the first products on the market to produce an ingestible formula made from only natural ingredients.


What Are the Ingredients?

Nugenix by Instaflex is a compound comprised of a proprietary blend of ingredients such as:

  • L-Citrulline Malate
  • Testofen
  • Tribulus terrestris

Each of these ingredients has been proven in clinical studies to enhance muscle density, size and strength and are used at maximum levels in this supplement.

Other ingredients in Testosterone Booster are:

  • 2mg of Vitamin B6
  • 50 micrograms of Vitamin B12
  • 5 mg of zinc



Nugenix is one of the few products on the market that aims to educate its consumers about diet, nutrition, the proper usage of testosterone boosters and the benefits a testosterone booster can deliver to men of all ages who seek overall wellness, fitness, health and increased muscle mass and strength. This product is also gaining popularity because its active ingredients are at the maximum strength; not all products can make that claim honestly. Lots of enhancement products on the market today may contain key ingredients, but the amounts of those ingredients in the actual supplements are minimal, leaving the consumer feeling disappointed as if they themselves have failed. Testosterone Booster promises max ingredients for max results, period.



Nugenix is manufactured in American laboratories under the strict guidance of the FDA Good Manufacturing Practice (GMP) standards. It is cGMP certified by FDA guidelines. The company Nugenix is also certified by the Better Business Bureau with an “A” rating.



Customer reviews of Nugenix say that they feel more energetic, more youthful and their stamina and performance has increased significantly with the use of this product. As with any testosterone booster, you will also experience an increase in overall mood, muscle density and physical strength. Many Nugenix customers are professional bodybuilders and say that the natural ingredients that are in Testosterone Booster makes them feel better about taking something natural rather than a synthetic hormone or a product that may contain a banned substance.



Nugenix received GNC’s Top Honor Vendor Award in 2013, named “Best Product Innovation” by GNC. Testosterone Booster, which is made from a proprietary blend of natural testosterone enhancing ingredients has obviously made an impact on today’s consumers and is thus the proud recipient of the Top Honor Vendor Award distinction. It is a prestigious award and it is no surprise that Nugenix is one of Direct Digital’s top selling supplements for men’s health today.


Media Coverage

There have been studies published in health journals about Testosterone Booster and the use of Testofen, the active ingredient in Nugenix. In the 2011 issue of Phytotherapy Research there was a study that involved men taking 600 mgs of Testofen every day for six weeks. The men in this study reported that they felt an increase in their stamina, muscle density and strength.
