How Does It Work?

Star MKII contains some powerful ingredients which can raise levels of testosterone in men, leading to greater muscle bulk and strength. It may also elevate the libido and boost sexual performance.

The formula also includes substances that can ease exercise recovery and help elevate performance. A study on mice in the Journals of Gerontology found that testosterone improves the regeneration of skeletal muscle [1].

Star MKII can burn fat by transferring fatty acids to cells for use as fuel, and this can give you additional mental and cognitive energy. It can also lead to weight loss but will not sacrifice your lean muscle mass.

This product also has cognitive health benefits. There are ingredients that raise levels of key brain chemicals involved in memory, learning, and mood like acetylcholine. This can enhance cognitive performance. An article in Current Opinions in Neurobiology examined the role of acetylcholine in learning and memory [2].

Star MKII is rich in antioxidants, which work to eliminate free radicals and lessen oxidative stress. This promotes healing in the body and strengthens the immune system.

Star MKII Ingredients – Are they Safe & Effective?

These are some of the primary active ingredients in Star MKII:

Tribulus Terrestris

– This herb is a testosterone booster that can greatly enhance muscle mass and strength. It also has antioxidants that strengthen the immune system and may help with muscle repair. A review in the Journal of Dietary Supplements discussed the aphrodisiac and performance-enhancing effect of this herb [3].

Eurycoma Longfoila

– This herb has a long history of use as an aphrodisiac. There’s evidence that it can increase testosterone levels and thus improve muscle mass and strength [4]. In addition, it may provide extra energy. A review in the Chinese Journal of Natural Medicines reviewed the evidence for this plant as an adaptogen for sexual health [5].

Acetyl L-Carnitine

– This is an amino acid which is a type of L-Carnitine. It delivers fatty acids to the cells for fuel, and there’s some evidence this leads to fat-burning and decreased BMI. It also boosts the activity of cells in the central nervous system [6]. A review in Obesity Reviews concluded that L-carnitine can lead to weight loss in adults [7].
