Are you looking to gain an extra edge at the gym, boost your lean muscle gain, or just increase your libido in the bedroom? Theoretically, this is what an increase in testosterone can provide you with. 

Testosterone boosters contain substances that can be used for the purpose of increasing testosterone levels in the blood, and in this particular article, we’re going to look at Ferodrox, a formula developed by Kaged Muscle.

We’re going to look at each ingredient within Ferodrox and evaluate based on the scientific literature available whether or not it’s got what it takes to increase your testosterone levels. 

Kaged Muscle’s Ferodrox Ingredients & Benefits

Zinc Monomethionine (30mg)

Different forms of zinc contain different amounts of elemental zinc, which refers to the weight of the zinc molecule by itself, and zinc monomethionine is approximately 21% zinc by weight.

Compared to other forms of zinc such as zinc picolinate or zinc citrate, there isn’t much difference as they can all be absorbed by the intestines and be used by the body normally.

The reason nutritional brands include zinc in formulas designed to boost testosterone is that supplementing with zinc has been shown to improve testosterone levels and sperm quality. 1

However, bear in mind that zinc deficiencies are quite rare and you’re able to easily get adequate levels of zinc through a plant-based or omnivorous diet. 

KSM-66 Ashwagandha (600mg)

Ashwagandha, also known as Indian Ginseng, is an herb used in Ayurveda, the traditional medicine of India, and this particular herb is classified as an adaptogen, which means it may help your neurological system resist stress. 

It is widely known for its anxiolytic (anti-anxiety) and stress-relieving effects, and it also seems to be able to reduce cortisol levels, which can be supported by an impressive body of literature. 2, 3, 4, 5, 6, 7, 8, 9

There’s also a growing body of evidence that supports the role of ashwagandha in improving total sleep time and sleep quality in people with and without insomnia. 10

Ashwagandha also seems to be growing in popularity among athletes, with some studies reporting it may increase VO2 Max (maximum rate of oxygen consumption measured during exercise). 11 Preliminary evidence also suggests that it can improve upper and lower body strength, lower body power, and recovery. 12, 13, 14

There’s also evidence suggesting that Ashwagandha improves sperm quality parameters in men with fertility issues, and these are very recent studies. 15, 16

Ashwagandha is an ingredient that is on the rise and for good measure as scientific literature reveals that it plays a role in different systems in the body, so it is not surprising that Kaged Muscle uses it in many of its products. 

Eurycoma Longifolia Root Extract (200mg)

While there’s not as much scientific literature about Eurycome Longifolia as there is about Ashwagandha, this plant may play a role in increasing testosterone levels.

A 12-week randomized controlled trial assessed the effects of an EL extract on testosterone levels and quality of life in men, and found that supplementing EL resulted in an increase in total testosterone. 17

However, bear in mind that the study was funded by the company providing the Eurycoma Longifolia formulation, so there is clearly a conflict of interests, which is why you should take the study with a big pinch of salt.  

Shilajit (200mg)

Shilajit is essentially a mixture of minerals that are used traditionally in Indian medicine, and it’s still currently in the preliminary stages of research in the West.

Traditionally, it has been used as a vitality enhancer and adaptogen compound, and it’s historically regarded as having miraculous effects. 18, 19

One human intervention with 200mg Shilajit daily 90 days in infertile men was associated with an increase in testosterone by 23.5% in serum. 20

Although promising, more research is required to fully assess its effects on testosterone production. 

DIM (Diindolylmethane) (120mg)

DIM is a molecule that is often found in vegetables such as broccoli, kale, and cauliflower, and it appears to exert powerful effects on estrogen metabolism, keeping the body relatively stable. 

Although it doesn’t directly increase your testosterone levels, its ability to inhibit the aromatase enzyme can prevent the conversion of testosterone into estrogen. 

Bioperine (10mg)

Piperine is the active component in black pepper, and the reason why many companies include this component in their supplements is that they wish the increase the bioavailability of the other elements in the formula, allowing your body to more efficiently absorb them.

However, this effect can only occur in compounds that are glucuronidated (such as curcumin), so it may not be effective in every scenario. In this supplement, its use may not be justified. 

Kaged Muscle’s Ferodrox Price

Ferodrox is not particularly affordable for a testosterone booster, but it uses unique, patented ingredients, which obviously make a supplement more expensive. 

One canister of Ferodrox costs $49.99, equivalent to $1.66 per serving, which makes it a bit more expensive than low-end testosterone boosters. However, Kaged Muscle allows you to get a monthly subscription and save 10% on Ferodrox, which is a good option, but only if you intend to take it medium to long-term.

Is Kaged Muscle’s Ferodrox Worth It?

Frankly, there are several ingredients that have tremendous potential, namely KM-66 Ashwagandha which has an incredible body of evidence that points to several benefits, including stress relief, improving sleep quality, increasing VO2 Max, and even potentially increasing upper and lower body strength.  It also plays a role in improving sperm quality in individuals with fertility issues.

Ashwagandha alone makes Ferodrox an efficacious supplement, but bear in mind that the other ingredients lack sufficient scientific evidence, so it’s possible that their effects may be lackluster. Do you wish to purchase a supplement where only one ingredient is bringing 90% of the results? This is a difficult question to answer, particularly because you don’t know whether the other ingredients are actually effective (as there’s not sufficient proof) and you can purchase Ashwagandha as a standalone supplement.

With that being said, you could give Ferodrox a try, and see if it works for you, specifically when it comes to increasing testosterone, as it’s what the other ingredients are intended to do.
