Ingredients in-depth

The dynamic duo of Vitamin D and Vitamin K2 is crucial for your overall health and well-being. Vitamin D acts as the catalyst, triggering the production of vitamin K-dependent proteins that rely on vitamin K for proper function. This powerful combination not only supports bone health but also orchestrates a harmonious dance regulating calcium metabolism, fortifying your skeletal system. It's crucial to supplement with both Vitamin D and Vitamin K, ensuring a nutritional balance that sidesteps the risks of soft tissue calcification and cardiovascular issues that are associated with stand alone vitamin D supplementation.

Vitamin D3 is one of a collection of vitamins that are essential for human function. Vitamin D3 is known to help regulate over one thousand biochemical and enzymatic reactions and functions. The most commonly known functions being the facilitation and regulation of the absorbtion of the minerals calcium & phosphorus needed for healthy mineralisation of bone. However vitamin D3 is much more than just a vitamin, it's actually a steroid hormone. In fact, one study in particular, showed thatthe effect of vitamin D supplementation on testosterone levels in menlead to a significant increase in testosterone. Although good amounts of naturally occurring vitamin D3 are found in eggs, fish and seeds, Test-FX is "mega" dosed with D3 to ensure maximum testosterone output.

Vitamin B6 is what we call a coenzyme (enhances the action of another enzyme) for over 100 enzyme functions in the human body. The most relevant functions in this instance being the metabolism of amino acids and is therefore critical to optimum growth and repair of skeletal muscle tissue.


The trace mineral Zinc is an important micronutrient that is essential for the maintenance of good health.  For example, adequate levels of Zinc are necessary for proper immune system function.

With a multitude of other physiological effects, Zinc also appears to be an important co-factor in sleep quality with emerging evidence consistently demonstrating that oral zinc supplementation may increase both the duration and the quality of sleep.

Magnesium is an essential mineral responsible for various different biological actions including the metabolism of ATP, electrolyte function, and is a significant structural element in DNA and other tissues of the body. In addition, Magnesium also plays a key role in the regulation of sleep, sleep time, and sleep efficiency. Furthermore, numerous studies also demonstrate Magnesium’s capacity to reduce serum cortisol concentration.

Selenium is an essential mineral with impressive anti-oxidant capabilities. Its incorporation into biologically active peptides known as seleno-cysteine, plays a crucial role in regulating anti-oxidant function (redox status) in nearly all areas of the body.  As a result of inclusion in to seleno-proteins, selenium acts as a donor of the amino acid cysteine; a rate-limiting factor of glutathione synthesis. Glutathione is the body’s master antioxidant and has a profound effect on the lymphocyte cells of the immune system, which favour high levels of glutathione for proper function. Selenium is therefore able to strongly influence inflammatory and immune system responses.

Testofen, a high-quality standardised Fenugreek Seed Extract, is renowned for supporting natural testosterone. It operates through furostanolic saponins, stimulating luteinising hormone production, and as a result, triggering testosterone synthesis. This botanical not only supports vitality but also amplifies your overall well-being. 

KSM-66 Ashwagandha is widely Known for its ability to support natural testosterone production. Its adaptogenic properties combat stress, helping to balance cortisol levels that can otherwise inhibit testosterone. Elevate not just your hormones, but your overall well-being with this evidence-backed, natural marvel.

Ginseng Korean Extract, a natural ally in promoting testosterone production. Its active compounds, like ginsenosides, foster enhanced blood flow, and surges in levels of key hormone-related enzymes which have been shown to induce the increased production of testosterone both in vivo and in vitro. By bolstering hormonal balance, this extract contributes to increased vitality and overall well-being. 

Grape Seed Extract, a natural fruit-derived compound boasting aromatase inhibiting properties and robust antioxidant protective capabilities. As a natural ally, it supports the delicate balance between testosterone and estrogen levels, fostering hormonal harmony. Its unique attributes help to shield against oxidative stress and aid in maintaining optimal hormonal equilibrium.

Maca, a nutrient-rich root from the Andes of Peru, is known for its adaptogenic properties and is also celebrated for its prowess in kindling male energy and hormonal balance. Maca may also help maintain a balanced mood and promote a sense of well-being. Its rich profile of vitamins, minerals, and antioxidants contributes to general wellness.

Stinging nettles are one of the plants you may want to avoid touching, however ingestion of this powerful plant can have some great health benefits. Stinging nettles do not actually act as a Testosterone booster; rather they play their part in the Test-FX formula by helping to keep your Oestrogen levels in check. Extracts of Stinging nettles contain compounds that have been shown to inhibit the Aromatase enzyme which is responsible for converting increased levels of Testosterone to the female hormone Oestrogen. Stinging nettles have also been shown to have a mild anti inflammatory effect and may even aid in the relief of Benign Prostatic Hyperplasia (BPH).

Why Test-FX® is Different

Most testosterone support formulas rely on over exaggerated claims, weak dosing, or overly complicated blends that may look impressive on the label but are under-dosed and under-deliver in real life.

After all you need the right balance between the number of ingredients and the amount of each ingredient.

Test-FX® was built differently. It combines carefully selected natural extracts, essential minerals, vitamin D3, K2, ZMA®, KSM-66® and Fenugreek extract in a full 5-capsule serving, allowing room for a more complete and optimally dosed formula.

No hidden blends. No over-inflated claims. No macho nonsense. Just a transparent, properly built men’s health formula designed to support healthy testosterone levels, energy, performance, drive and daily vitality.

Frequently Asked Questions

This can vary significantly from product to product. Test-FX is designed to support stress, sleep, nutrient status and training recovery. Test-FX uses ingredients such as KSM-66® ashwagandha, fenugreek, ZMA, vitamin D3 and selenium to support male performance naturally. Well-documented human studies show these ingredients are most effective at supporting healthy testosterone in men.

Test-FX is not built on hype or mega-dose mystery blends. It combines branded, evidence-led ingredients with key minerals and vitamins linked to normal testosterone production, muscle function and wellbeing. In addition, every ingredient is effectively dosed, which is why each serving is 5 capsules.

Some men notice better drive, mood or training motivation within a few weeks, but the best results usually come from consistent daily use over 4–12 weeks. For example, Ashwagandha trials commonly run for around 8-12 weeks.

If your levels are already within a normal range, do not expect steroid-like changes. Test-FX is designed to support healthy testosterone, stress resilience, recovery and general male wellbeing, by providing the body with key essential ingredients required for optimal hormone synthesis.

Test-FX is designed for daily use when taken as directed. Aside from any hormonal benefits, Test-FX contains essential ingredients that the body requires on a daily basis which are consequentially considered crucial for your health.  Therefore Test-FX is perfectly safe to be consumed every day.

No. Test-FX is a natural testosterone support supplement using plant extracts, vitamins and minerals to support healthy male physiology.
