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.*

Kaged has surpassed my expectations. The taste, the ingredients and mixability of products is awesome. Love this brand, so far I have had two of my workout partners do the switch to Kaged as well.

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.*
