There are lots of support for many ingredients, some of which have been used for thousands of years. Regulatory bodies require major scientific studies on ingredients to be EFSA approved. The following ingredients have no official UK or EU authorised health claims associated with them as studies and research show they have various and mixed results; however some approvals are pending and many people swear by them as they have been used for centuries – so this is for information only!

Training at approximately 60-70% of maximum heart rate (zone 2) has proven to increase the amount of mitochondria in the cells, which improves the body’s ability to produce energy aerobically (with oxygen) as well as utilize fat for fuel. Training at this intensity also increases amount of capillaries in the muscle. This helps deliver nutrients into the muscle while removing waste products.

Males tend to have a higher maximal oxygen uptake (VO₂max) due to having larger hearts, more muscle mass, more hemoglobin as well as less body fat than females. However, females often have proportionally more fatigue-resistant slow-twitch muscle fibers than males do. Some studies have even hinted that females may be able to burn fat for fuel more efficiently, which may be a result of estrogen’s (female sex hormone) effect on the metabolism.

To understand the mechanics of endurance capability, we must first take a look at how the cardiorespiratory system works. Andro 400 is formulated with natural ingredients, including Eurycoma Longifolia, to improve men’s performance and energy levels. Wankhede S, Mohan V, and Thakurdesai P.

The basics of endurance

Phytotherapy Research – Recent research has shown that “Fenugreek extract has a significant effect on total serum testosterone.” These results were reported in 2020 and based on a review of all available research to date.

Plasma accounts for approximately 55% of all fluid in the blood. 92% of plasma is water, whereas the remaining 8% consists of glucose, proteins, fats, hormones, minerals, and vitamins. The remaining 45% of the blood consists of red blood cells, white blood cells, and platelets. Haskell CF, Kennedy DO, Wesnes KA, et al.
