THE "KING" HORMONE

Testosterone is the king hormone for all things building muscle, boosting strength, and living with vitality.

However, testosterone levels fluctuate due to age, stress, diet, and more.

Whereas most “testosterone booster” supplements include 1 or 2 unproven ingredients in unsound (or straight-up unknown) doses,Ferodrox pushes the envelope with 6 ultra-premium ingredients that help create the ideal anabolic environment for building muscle and strength.*

TRANSPARENT, TESTED DOSES

For every one of our ingredients, we looked directly at the latest scientific research, and tested and tweaked our formula to find the ideal dose.

Many testosterone boosters use “proprietary blends” to avoid disclosing how much of each ingredient they use. In contrast,the Ferodrox formula is fully disclosed, so you know exactly how much of each ingredient you're getting.

 

HOLISTIC FORMULA

With patented ingredients backed by scientific research, you know you are getting a supplement that can help increase muscle mass, optimize cortisol levels, and keep testosterone levels in the normal healthy range. Plus, we use vegetable capsules to make sure the delivery system is clean for your body.*

KNOW YOUR INGREDIENTS

LJ 100® TONGKAT ALI // TESTOSTERONE SUPPORT 

200 MILLIGRAMS PER SCOOP

LJ100® Tongkat Ali, or Eurycoma longifolia, is the only science-based Eurycoma longifolia extract, standardized to precise percentages of TA’s bioactive compounds. Co-discovered and researched in collaboration with MIT, patented LJ100 has been shown to have pro-androgenic effects.*[1]

Evidence suggests that LJ100 may increase the bioavailability of testosterone by lowering the amount of sex hormone binding globulin, or SHBG, and reducing the conversion of testosterone to estrogen.*[3,4] Around age 30, SHBG begins to naturally increase.

In a study published in the Journal of the International Society of Sports Nutrition, subjects with moderate stress supplemented with 200mg of LJ100. After four weeks, cortisol levels decreased while testosterone levels increased.* Overall, the anabolic environment—using the ratio of circulating total testosterone compared to cortisol—improved significantly.*[2]

KSM-66 ASHWAGANDHA® // CORTISOL MAINTENANCE

600 MILLIGRAMS PER SCOOP

KSM-66 Ashwagandha root extract works as an adaptogen to help maintain healthy cortisol levels.* The Ferodrox formula delivers a precise 600mg of KSM-66 Ashwagandha which has been shown to lower serum cortisol levels.*

In a randomized, double-blind, placebo-controlled study, researchers gave 64 subjects 600mg of KSM-66 or a placebo for eight weeks. At the end of the study, the KSM-66-supplemented individuals had decreased their cortisol levels significantly versus the placebo.*[5]

Research has also shown that supplementing with 600mg of KSM-66 Ashwagandha daily can increase strength, muscle mass, and total testosterone, while reducing body fat [6].* Supplementing with KSM-66 while also resistance training three times per week, for a period of 12 weeks, resulted in:

  • Increases in bench press and leg strength*
  • Increases in chest and upper arm size*
  • Improvement versus placebo for change in body fat*
  • Increase in total testosterone within the normal healthy range*

KSM-66 is derived from a solvent-free water extraction technology which results in a full spectrum extract. In fact, KSM-66 has the highest percentage of naturally-occurring withanolides of root-only extracts available on the market today, with more than 5% concentrations as measured by HPLC.

This cutting-edge, premium patented ingredient is backed by the most extensive research of any Ashwagandha available, cementing our decision to include it in the Ferodrox formula.

BIOPERINE® BLACK PEPPER EXTRACT // ENHANCED ABSORPTION

10 MILLIGRAMS PER SCOOP

It’s not what you take, it’s what you absorb. 

Ferodrox contains 10mg of BioPerine®, a purified extract of black pepper that works to help enhance absorption of our other ingredients.* BioPerine® is the only piperine supplement with rigorous clinical evaluation to establish its safety and efficacy.

PRIMAVIE® PURIFIED SHILAJIT // ADAPTOGENIC SUPPORT

200 MILLIGRAMS PER SCOOP

PrimaVie is a clinically studied, premium standardized shilajit that helps support testosterone levels in the healthy range.

PrimaVie standardized shilajit extract is manufactured using state of the art chemical-free aqueous processing technology, to ensure you are getting consistent quality. In addition, PrimaVie® undergoes a proprietary purification process and is self-affirmed GRAS (Generally Recognized as Safe).

It contains over 40 different minerals, and comes from high-altitudes in the Himalayan mountains. Shilajit is an important tool of the ayurvedic and has been used for over 3,000 years as an adaptogen in a variety of situations.

L-OPTIZINC® // OPTIMAL HEALTH

30 MILLIGRAMS PER SCOOP

Zinc, an essential mineral, plays a crucial role in enzymatic reactions[8] and is essential for supporting testosterone production. The average male requires roughly 11mg of zinc daily. Balancing micronutrient intake is one of the key factors in maintaining testosterone levels within the normal healthy range.*

However, the benefits of this important mineral are dependent on the amount of zinc that is actually absorbed and utilized by the body.The zinc used in the Ferodrox formula is a highly absorbable and premium patented form of zinc.

L-OptiZinc, which is zinc bound to methionine, has been scientifically shown to be absorbed better and sustain higher plasma levels compared to some other zinc forms.*[11] Ferodrox includes 30 mg of patented L-OptiZinc® zinc L-monomethionine in each daily serving.

3,3'-DIINDOLYLMETHANE // ESTROGEN MAINTENANCE

120 MILLIGRAMS PER SCOOP

Preliminary research suggests that 3,3'-Diindolymethane, or DIM, can help maintain estrogen levels within the normal healthy range, which in turn could help maintain testosterone levels within the normal healthy range.*

It’s a powerful phytochemical derived from cruciferous vegetables like broccoli and cauliflower. The Ferodrox formula contains 120mg of an ultrapure, bioavailable form of benzene-free DIM.
