Yes. Beyond the athletic advantages provided by GPS Circulate, there are additional physiological effects that are often noted from its use. These can arise from vascular effects of the nutrient composition, (those resulting in the more efficient delivery of nutrients/oxygen throughout the body) as well as from the support of HGH (human growth hormone) release from the pituitary and from supported production of the neurotransmitter GABA (gamma aminobutyric acid). The key ingredient in GPS Circulate is L-arginine, an amino acid that works by increasing nitric oxide levels in the body and improving the elasticity of the arteries, thus facilitating increased blood flow. These physiological effects can include quicker recovery, improved mood/anxiety levels, increased muscle mass and heightened sexual function in men and women. GPS Reset also supports sexual function and/or performance in both men and women. * GPS Adapt, which helps minimize a feeling of anxiousness, can also help improve sexual performance. These products are not recommended for anyone younger than 18 years of age.
