Details on Ingredients

Tribulus Terrestris: An herbal supplement that’s supposed to “produce large gains in strength and lean muscle mass,” according to the Journal of Strength and Conditioning Research. However, the study revealed no increase in gains with supplementation for five weeks. The Journal of Human Kinetics published a study that claimed, “The Australian Institute of Sport does not recommend athletes’ usage of TT [tribulus terrestris]. So far, the published data concerning TT do not provide strong evidence for either usefulness or safe usage in sport.” 

Diindolylmethane (DIM): Though no definite benefits in humans have been produced in clinical research, animal research suggests taking DIM is safe, based on a study in the journal Laryngoscope.

L-Arginine: An amino acid with amazing health benefits, including positive effects on exercise training. “L-arginine augments the effects of exercise training on insulin sensitivity and capillary growth in muscles,” according to research published in Current Opinion in Clinical Nutrition and Metabolic Care

Mucuna Pruriens Seed Extract: A review of research published in the Journal of Traditional and Complementary Medicine claims, “all parts of the Mucuna plant possess medicinal properties.” 

Shilajit Extract: An extract that oozes from the mountains in the Himalayas, shilajit extract may positively affect male vitality and fertility, according to the journal Andrologia.

Fenugreek Extract: According to NCCIH, “We have little conclusive evidence about the effects of fenugreek on health conditions, though we do have a fair amount of information on its possible side effects.” 

Eurycoma Longifolia: Clinical research has shown that eurycoma longifolia may “elevate serum testosterone and increased muscle strength in humans,” according to the International Journal of Preventive Medicine

Guarana Seed Extract: A stimulant used similarly to caffeine. This extract is often added to weight-loss pills and performance supplements. 

American Ginseng Root: Provides antioxidative and anti-inflammatory effects, especially when fermented in the fashion of probiotics, according to research in the Journal of Pharmacy and Pharmacology

Bitter Orange Fruit Extract: Based on information from NCCIH, “Applying bitter orange oil to the skin may help with ringworm, jock itch, and athlete’s foot infections. There’s not enough scientific evidence to support the use of bitter orange for other health purposes.” 

Yohimbe Bark Extract: Research published in the journal Urology claims yohimbe benefits outweigh the risks. It may be useful as an initial intervention for erectile dysfunction.”
