    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 peak 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 faster and more effectively you can bring cortisol under control the greater your total anabolic environment and better your recovery.* 

    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 by over 16% while testosterone levels increased by 37%!* Overall, the anabolic environment—using the ratio of circulating total testosterone compared to cortisol—improved by an incredible 36%.*[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 increase steadily.

    LJ100 is the only Tongkat Ali clinically proven to maintain testosterone levels within the normal healthy range.* This powerful patented ingredient is backed by 13 human studies, and has proven efficacy and safety. Made from wild-crafted Tongkat Ali root from the rainforests of Malaysia, it's produced using a proprietary extraction technology.


    KSM-66 Ashwagandha (Withania somnifera) root extract works synergistically to help reinforce the powerful effects of LJ100 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 by more than 266% versus the placebo.*[5]

    Research has also shown that supplementing with 600 mg of KSM-66 Ashwagandha daily can increase muscle mass, total testosterone, and strength, reduce bodyfat[6], and enhance endurance[7].* In fact, supplementing with KSM-66 while also resistance training three times per week, for a period of 12 weeks, resulted in:

    • Up to 139% and 52% increases in bench press and leg strength*
    • Over 3% and 17% increases in chest and upper arm size*
    • More than 128% improvement versus placebo for change in bodyfat*
    • Over 15% increase in total testosterone*

    KSM-66 is the world's most effective and pure, 100% organic certified Ashwagandha root extract in existence. It's derived from a proprietary alcohol and solvent-free, water extraction technology which results in a highly concentrated, full spectrum extract that preserves an optimally effective balance of natural constituents of the herb. 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 and negligible levels of the undesirable Withaferin A.

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


    PrimaVie is a clinically studied, premium purified shilajit containing dibenzo-a-pyrones (DBPs), DBP-Chromoproteins (DCP), fulvic acid and 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 remedy of the ayurvedic and has been used for over 3,000 years as a rejuvenator and adaptogen in a variety of conditions.

    Together, pure shilajit and Ashwagandha is a powerful combination. Historically, the combination has been used widely as an effective supplement to boost energy levels, and improve libido and overall health.* Ferodrox contains 200mg of PrimaVie purified shilajit to help amplify the effects of KSM-66 Ashwagandha and LJ100® Tongkat Ali, unlocking their powerful synergistic effects.*

    PrimaVie purified shilajit extract is manufactured using state of the art chemical-free aqueous processing technology, to eliminate any impurities and maximize potency. In addition, PrimaVie® undergoes a proprietary process to remove harmful heavy metals and is GRAS affirmed and Proposition 65 compliant. Many other generic forms of shilajit have been found to contain high levels of arsenic and fail to meet the standards set out by Proposition 65.


    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], immune system function[9,10], and protein synthesis[10]. The average person requires roughly 10-15mg of zinc daily to support crucial endocrine functions.* In fact, balancing micronutrient deficiencies 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 organically bound to methionine, has been scientifically proven absorbed better and sustain higher plasma levels compared to 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. Research shows that DIM helps maintain estrogen levels within the normal healthy range, which in turn helps maintain testosterone levels within the normal healthy range.*

    The Ferdrox 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 from starting materials that contain benzene, a toxic chemical compound that is a known carcinogen in high levels. The DIM used in Ferodrox has been thoroughly tested and proven to be benzene-free. Also, DIM consumed on its own or in regular capsule form, is ineffective. Ferodrox utilizes BioPerine black pepper extract and an innovative capsule technology that enhances the absorption and bioavailability of DIM.*


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