Study: Citrulline/malate promotes aerobic energy production in human exercising muscle.
Source: Bendahan D, Mattei JP, Ghattas B, et al. British Journal of Sports Medicine. 2002;36(4):282-289.
Results: Intake of L-citrulline malate promoted aerobic energy production in working muscles.
L-Ornithine HCL:
Study: Oral ornithine supplementation attenuates physical fatigue in healthy volunteers by modulating lipid and amino acid metabolism.
Source: Sugino T, Shirai T, Kajimoto Y, et al. Nutrition Research. 2008;28(11):738-743.

Study: Zinc status and serum testosterone levels of healthy adults.
Source: Prasad AS, Mantzoros CS, Beck FW, et al. Nutrition. 1996;12(5):344-348.
Results: Zinc deficiency was associated with lower testosterone levels; supplementation increased testosterone levels in zinc-deficient men.
Black pepper extract (piperine):
