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.*

Frequently asked questions

Test (Ferodrox)

Who is Ferodrox for?

Ferodrox is ideal for men looking to support healthy testosterone levels, increase muscle mass, and improve overall strength. It’s particularly beneficial for those over 30, when testosterone levels naturally decline.

When should I take Ferodrox?

Take 2 capsules in the morning or 1 capsule in the morning and 1 capsule in the afternoon, preferably with food.

Ferodrox is safe to take daily for an extended period of time. All of the ingredients have been thoroughly tested for safety and efficacy.

How does Ferodrox support healthy testosterone levels?

The Ferodrox formula contains six patented key ingredients to support healthy hormone levels.

For testosterone, the star ingredient in this formula is LJ100 Tongkat Ali, or Eurycoma longifolia. This is the only science-based Eurycoma longifolia extract, standardized to precise percentages of TA’s bioactive compounds.

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.* Around age 30, SHBG begins to naturally increase.

How does Ferodrox manage healthy cortisol and stress levels?

TEST Elite uses KSM-66 Ashwagandha, a potent adaptogen shown to help manage cortisol levels. By helping to manage cortisol levels, it helps maintain a hormonal balance, essential for muscle growth and overall health.*

Q&A

I don't eat breakfast, so my first meal is around 14:00. Do you recommend taking 2 pills in the morning without food? What will be the decrease in the potency?: Thank you for your question! We suggest consuming our product with food primarily to prevent potential upset stomach issues. The effectiveness of the product remains unchanged; however, taking it on an empty stomach might lead to stomach discomfort. Every individual has unique preferences; some may opt for an empty stomach intake of products like Ferodrox, while others may prefer it with food. If choosing to take it on an empty stomach, we advise gauging your tolerance by starting with one capsule in the morning and the second at lunch. If you experience no stomach discomfort, you can try taking both capsules in the morning and assess how you feel. It's also advisable to seek personalized advice from your healthcare professional.
I'm a bit concerned about the amount of Zinc. Usually the upper limit is 40mg. And this having 30mg. I could easily reach that limit from other dietary sources. Is it safe to take in the long run? Should I take a cooper supplement? What are the risks?: Consuming amounts under 40mg/day is a safe amount to take over time however, it’s recommended that you consult with your healthcare provider for specific recommendations related to your zinc intake. Zinc is an essential mineral, and while it is necessary for the body in appropriate amounts, taking too much can have adverse effects. Your physician can assess your individual health, consider your medical history, and provide personalized advice on the appropriate dosage of zinc, as well as any potential interactions or side effects.
Is there anything I should be taking along with this besides a multivitamin? I currently take Animal Pak, has a liver support conplex, but want to make sure I don’t need to add an estrogen blocker as well.: Ferodrox is a dietary supplement that features several ingredients designed to support testosterone within the normal, healthy range for men and to provide other benefits related to maintaining an optimal hormonal environment for bodybuilders. But it's important to note that the product does not contain exogenous testosterone (e.g steroids or Testosterone Replacement Therapy [which are drugs]). Kaged includes scientifically tested ingredients such as KSM-66®, LJ100®, PrimaVie®, and L-OptiZinc® that have been shown to boost testosterone and promote an anabolic environment in men, using minerals and herbal ingredients. But all of this is designed to boost and maintain testosterone within the normal, healthy range -- not to supply or replace testosterone. So the testosterone boost within the normal, healthy range should not result in the side effects sometimes associated with steroids or hormone drugs that may call for the use of estrogen blockers.
Is there any side effects in terms of mood swings or increased aggravation/anger issues?: Ferodrox is a dietary supplement that features several ingredients designed to support testosterone within the normal, healthy range for men and to provide other benefits related to maintaining an optimal hormonal environment for bodybuilders. But it's important to note that the product does not contain exogenous testosterone (e.g steroids or Testosterone Replacement Therapy [which are drugs]). Kaged includes scientifically tested ingredients such as KSM-66®, LJ100®, PrimaVie®, and L-OptiZinc® that have been shown to boost testosterone and promote an anabolic environment in men, using minerals and herbal ingredients. But all of this is designed to boost and maintain testosterone within the normal, healthy range -- not to supply or replace testosterone. So the testosterone boost within the normal, healthy range should not result in the side effects sometimes associated with steroids or hormone drugs.
Is there any benefit to taking 3 pills a day? Possibly 2 in the morning and 1 in the afternoon.: Hello! No, there is no advantage to be gained by taking more than the recommended servings per day. We generally recommend taking 2 capsules in the morning or one in the morning and one in the evening.
Is this product tested to be safe for powerlifting athletes by USAPL and USADA standards? USADA has a drug lookup tool but the ingredients are showing up as "not found" in their database so taking can be a risk if it's not certified to meet their standards.: Kaged uses third party banned substance testing companies for many of our products (LGC's Informed Sport for most Kaged sports nutrition products and BSCG for original Clean Burn). Both of those testing/certification companies focus on the WADA banned substance list. However, neither of those certification companies, nor any of the other recognized third party banned substance testing companies, will cover ANY product in the testosterone support category. This is due to the perceived risk in the category and unfortunately it leaves athletes to have to check with their own governing bodies about the permissibility of any ingredients or products they intend to use. So you would need to discuss the ingredients in Ferodrox with your governing body, since the supplement is not eligible for third party testing/certification programs. Best of luck in your training and competitions!
When is the best time to take the dose? Before? After a workout? Or before going to sleep?: Hello, You should take Ferodrox according to the Directions on the label: Take 2 capsules in the morning or 1 capsule in the morning and 1 capsule in the afternoon, preferably with food.
Is this product safe for a woman to take? Even if it's not long-term? If it is safe, are there any side effects for a woman?: Hey there! Great question, Ferodrox features several ingredients to support testosterone within the normal healthy range for men and other benefits related to maintaining an optimal hormonal environment for bodybuilders. Although the product does not contain exogenous testosterone (e.g steroids), it's ingredients have been primarily studied on male subjects. So while it should be safe for female bodybuilders, it was primarily designed for males.
Is this a product you can take regularly, or do you need to take a bottle and “down cycle” after?: That is a great question! This is a product you can take continuously but if you'd like to take any time off, you can usually take a week or so off in between bottles.
What is the proper dosage of ferodrox to take? I have a bottle that states 'take 1 pill twice a day', but a previous bottle stated 'take 1 dose, 2 pills, twice a day'.....which is correct?: Hi Charles, Thank you so much for the question! That's great that you asked this and will be more than happy to help answer it. We recommend taking 2 capsules in the morning or 1 capsule in the morning and 1 capsule in the afternoon, preferably with food. Please reach out to our customer service team at Support@KagedMuscle.com if you have any other questions.
Do you need to cycle Ferodrox?: Great question! We recommend taking the Ferodrox for 6-8 weeks on and 1-2 weeks off. Please reach out to our customer service team at Support@KagedMuscle.com if you have any other questions.
Is this product plant based or does it have any animal sources?: That's an awesome question and I'm more than happy to help. Although it is not suitable for vegans, it is for vegetarians.
