What Are the Ingredients in Star MKII?
These are some of the primary active ingredients in Star MKII:
Eurycoma Longfolia – This is a plant which is a known aphrodisiac, as some evidence shows that it could raise levels of testosterone in the body [1]. This leads to great gains in lean muscle mass and strength, and it also boosts libido.
A study in the Chinese Journal of Natural Medicines found that this herb raised testosterone and elevated measures of sexual performance in male rats [2].
Acetyl L-Carnitine – This is an amino acid which may lead to fat-burning and weight loss [3]. It assists in bringing energy to the cells and increases levels of brain chemicals related to learning and memory. It can also help heal the muscles.
A review in Nutrients concluded that L-Carnitine plays an important role in muscle recovery [4].
Bulbine Natalensis – This is a plant which contains saponins and alkaloids. Research indicates that it’s a testosterone booster which can increase libido and sexual functioning [5]. In addition, it can elevate energy levels.
A review in the Journal of Applied Medical Science discussed the uses, as well as biological and chemical properties of this herb [6].
How Does Star MKII Work?
Star MKII may be the best testosterone booster for muscle gain. Rich in ingredients which increase levels, it can create great gains in muscle bulk and strength, as well as boost sexual libido. Other ingredients also increase muscle size and help with exercise recovery.
A study in Clinical and Translational Endocrinology concluded that a testosterone increase is related to improved muscle strength and physical performance [7].
Other ingredients assist in fueling the cells, which can help boost physical and mental energy. The transfer of fatty acids to the cells also burns fat, leading to weight loss without losing lean muscle mass.
An article in the International Journal of Environmental Research and Public Health discussed the role of antioxidants and exercise performance [8].
