Product Information


  • Helps Maintain Testosterone Levels Within the Normal Healthy Range*
  • Helps Maintain Testosterone and Cortisol Ratio Within the Normal Healthy Range*
  • Supports Increases in Lean Muscle Mass and Strength*
  • Helps Promote An Anabolic Environment* 

There's no question that testosterone is the king of muscle building hormones. For anyone wanting to add size, boost strength and performance, lose fat, maintaining a healthy testosterone-to-cortisol balance is critical. The problem is, testosterone levels can fluctuate, whether due to age, stress, diet, or just regular, intense training protocols.

Ferodrox™ is an industry breakthrough created to help you maintain testosterone levels within the normal healthy range.* Each ingredient was carefully selected and included in ultra-precise amounts to deliver unmatched results.* Unlike many other supplements on the market, the Ferodrox formula is fully disclosed, so you know exactly how much of each ingredient you're getting.


LJ100 Tongkat Ali, or Eurycoma longifolia, is the only science-based Eurycoma longifolia extract, standardized to contain not less than 22% bioactive "eurypeptides" and 40% glycosaponins. The bioactive "eurypeptides" are derived from the root of the plant. Co-discovered and -researched in collaboration with the esteemed Massachusetts Institute of Technology (MIT), the LJ100 patented Eurycoma has been shown to exert proandrogenic effects.*[1]

Each serving of Ferodrox delivers a powerful 200mg of LJ100 Tongkat Ali to encourage favorable hormone balance by combating cortisol and supporting optimal testosterone-to-cortisol ratio within the normal range.* Cortisol levels rise in response to frequent, intense training and other forms of physiological stress. Which, under healthy conditions, directly influences your body's testosterone response. The more effectively you can limit your cortisol, the better the conditions are for maintaining an anabolic environment.*

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, researchers measured stress hormones in the body and found that cortisol levels decreased while testosterone levels increased!* Overall, the anabolic environment—using the ratio of circulating total testosterone compared to cortisol—improved significantly.*[2]

Research is still unclear as to the precise molecular pathways and biochemistry, but 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] Once you hit biological maturity at about age 30, SHBG begins to naturally increase.

KSM-66 Ashwagandha (Withania somnifera) root extract works as an adaptogen in maintaining cortisol levels within the normal healthy range.* The Ferodrox formula delivers a precise 600mg of KSM-66 Ashwagandha which has been scientifically shown to significantly 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]

Increases in bench press and leg strength*

Increases in chest and upper arm size*

Improvement versus placebo for change in bodyfat*

Increase in total testosterone within the normal healthy range*

KSM-66 is the world's best Ashwagandha root extract in existence. It's derived from a proprietary alcohol and 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.



Not all Ashwagandha extract is created equal. Follow this guide to ensure you're getting a premium Ashwagandha extract supplement:

The Ashwagandha extract is drawn from roots alone and no leaf components have been added

The research studies are published in credible peer-reviewed, academic, and refereed journals such as those indexed on PubMed

A number of the published studies on Ashwagandha extract have been conducted on normal, healthy populations

The Ashwagandha extract is a full spectrum extract

PrimaVie is a clinically studied, premium standardized shilajit containing over 40 different minerals. This powerful organo-mineral compound is obtained from sedimentary rocks in the Himalayan mountains at altitudes between 1000 and 5000 meters. 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.

Together, shilajit and Ashwagandha is a powerful combination.* Ferodrox contains 200mg of PrimaVie standardized shilajit to help support testosterone levels in the normal, healthy range.*


Zinc is one of 24 essential minerals; however, the body cannot synthesize its own, so it must be taken in via diet or supplementation. It plays a crucial role in enzymes[8] and is essential for supporting a normal anabolic environment. The average male requires roughly 15mg of zinc daily. In fact, 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'-Diindolymethane, or DIM, is a powerful phytochemical derived from cruciferous vegetables such as cabbage, broccoli and cauliflower. Preliminary research suggests that DIM can help maintain estrogen levels within the normal healthy range, which in turn could help maintain testosterone levels within the normal healthy range.*

The Ferodrox formula contains 120mg of an ultrapure, bioavailable form of DIM. It's important to note that not all formulas using DIM are effective due to their sources or delivery methods. Some companies use low quality sources of DIM. The DIM used in Ferodrox has been thoroughly tested to be benzene-free.

Ferodrox contains 10mg of BioPerine®, a purified extract of black pepper, or 95% piperine, that works to help enhance absorption.* BioPerine® is the only piperine supplement to have undergone rigorous clinical evaluation to establish its safety and efficacy, and has obtained patented status.


    With six high-quality ingredients working to help you turn into an unstoppable machine, Kaged Muscle researchers have created a monster with Ferodrox.* But Kaged Muscle scientists didn't stop at premium ingredients.
