FERODROX™: A SCIENTIFIC BREAKTHROUGH

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, and heighten sex drive, maintaining a healthy testosterone to cortisol ratio is critical. The problem is, testosterone levels can fluctuate, whether due to age, stress, diet, or just regular, intense training protocols. It can be near impossible to gain power over these fluctuations with most other dietary supplements.

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.

Our research team was tasked with sourcing the highest quality, patented ingredients backed by real science, with no cost limitations. In fact, some of the ingredients cost up to ten times more than the generic ingredients used by many of our competitors.

Many companies borrow claims from these premium patented ingredients, but use cheaper, poorer quality, generic materials that have not been proven to be effective. This unethical and deceitful marketing practice is far too common in the dietary supplement industry, and allows companies to increase their profits while giving you inferior ingredients. Any brand claiming that these cheaper, lower quality ingredients are as safe and effective as those that have been clinically researched and patented, simply aren't being truthful.

If your supplement isn't formulated with scientifically proven ingredients such as KSM-66®, LJ100®, PrimaVie®, and L-OptiZinc®, then it's time for a change.*
SCIENCE MEETS NATURE

Ferodrox's powerful matrix has six superior ingredients scientifically proven to amplify your results.*

LJ100® TONGKAT ALI

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®

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, 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-occuring withanolides of root-only extracts available on the market, 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® PURIFIED SHILAJIT

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.

L-OPTIZINC®

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[7], immune system function[8,9], and protein synthesis[9]. 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.*[10] Ferodrox includes 30 mg of patented L-OptiZinc® zinc L-monomethionine in each daily serving.

3,3'-DIINDOLYLMETHANE

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.*

BIOPERINE® BLACK PEPPER EXTRACT

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.

LJ100 13 Human Clinical Trials - Patent NO US 7,123,117 B2
UNLEASHING THE FURY OF FERODROX

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

Ferodrox's powerful ingredients are unleashed with its precise advanced delivery technology. Engineered with superior delayed release vegetable capsules, the ingredients in Ferodrox's formula begin to shuttle into your system within 20 minutes of reaching the stomach.* Unlike traditional capsules, this unique delivery technology allows the ingredients in Ferodrox to bypass the stomach and be rapidly taken up into the small intestines.* This means there is less threat of Ferodrox's ferocious power being destroyed in the low pH (acidic) of the stomach. The extended action of the unique delivery technology significantly reduces ingredient degradation compared with conventional, immediate release capsules used for most other products.

With dramatically enhanced absorption, Ferodrox™ can permeate your cells and begin to help stimulate gains in size and strength from virtually every conceivable angle.* Never in bodybuilding has a vegetable capsule technology so advanced been used to deliver the superior effects of such a revolutionary supplement.*

Awesome product. I used Ferodrox (along with clean burn) for 8 weeks during my contest prep and it definately made my cut more bearable. This is THE best (legal) fat loss combo that mine can buy. I went from about 9% body fat to 5% with this combo, and I actually GAINED strength. The Ferodrox adds a substantial amount of drive and focus that I now miss while taking a break. I will definately be using this combo again in the near future!

I'm a big fan of KM, however this product did nothing for me and I took it for a month, I was not expecting anything crazy, maybe a boost in the gym. I'm giving an 8 since it appears to work for others and I trust KM products.

Before this product, I thought I was just tired from wrestling,work and school but once I've started to take Ferodrox, I haven't been tired or neglected from my gym routine since and I've only been taking it for three weeks. Combined with my diet, I've been loosing body fat like crazy. I went to the doctors office and my testosterone levels are leveled out and normal so I'm very happy with this product and I will be using it for now on. Thank you Kris Gethin for actually caring for what we put in our bodies because before your products I've given up on supplements for 3 years so thank you for helping me with my health and I've reached a new level of fitness and I'm just going to keep growing. 10/10

I didn't notice anything but missing $60 in my bank account. I absolutely love KM but this just didn't do it for me. I'll stick with my DPol

Without a doubt I trust Kaged Muscle supps. I've used Ferodrox now for 2 months. Personally, I hadn't noticed much of a difference in my performance or my day to day activity level compared to other test boosters I've taken. Just my opinion on the matter, but no doubt Kaged Muscle has quality products that work, this one just isn't for me. IG @Patzius

First of all, I'll say that am not lacking test, but maybe on the lower quartile of expected ranges, so I was pumped to try this out an optimize the test I had. Overall, I faced some side effects (described below), but at times felt a bit stronger in the gym, and calmer (i guess less anxious?) in general. I don't know if I'll keep using it, as for me, the benefits didn't outweigh the cons, but I still think the profile and science behind it is solid af. My criticism was that it did give me a fair bit of brain fog. To describe, I felt a bit weak in mental sharpness and acuity. This went away after discontinuing use. As far as dosage, 4 caps made me feel more lethargic than usual. When I took 4 caps in the morning, I would be kind of useless for anything requiring energy or mental alertness. I dropped to 2 caps in the AM, and got better response (no issues, side effects), with no material decrease in the effectiveness of the product I had seen, so this ended up being my sweet spot.

I just finished my second bottle, so I have used it for two months. I was very excited to try this because of all the hype. From all information from Kris I had read about, I was under the impression this was a test booster. After I purchased it, then I read it is a "Test Normalizer". In other words, if you have low test, it may increase it, but it won't increase it above your natural levels. I was disappointed in reading this as I thought this was going to be the first test booster that actually did just that, increase your testosterone. I can say that after about two weeks of using it, however, my strength went up on several different lifts. It was not dramatic, but I do believe this product does help with strength. However, this was not long lived (about two weeks), and it seemed I did not notice any difference after that with the second bottle. This is just me, and it may be because I do not have low test, however given the high price, and the fact that I was assuming this was an actual test booster, I expected more.

i have been using this product for awhile now and i must say that it is the best test booster out there.I am currently on my third bottle and I love the results I have seen so far.

Verified Buyer

I haven't completed my cycle of using this, but like all the Kaged Muscle products with one is amazing. I definitely felt a difference with my recovery times within the first week of using it. Feeling that allowed me to push harder and make better progress in the gym, while still staying lean.

I’m about half way through my second bottle and the results are great. My strength has drastically increased along with my mood. This is the only test booster I’ve taken so I can’t compare to others but I love Ferodrox and would highly recommend it.
