Learning, memory, and intelligence all depend on adequate supplies of HGH. A team of Swedish Scientists discovered why HGH replacement therapy makes so many people feel so good. HGH acts in the brain exactly like an antidepressant, raising the level of the neurotransmitter B- endorphin, which has been called the brain's own opiate. It also lowers the level of dopamine, which is associated with feelings of agitation. It reverses the outlooks, expectations and attitudes associated with the aging process.
Many other experts expressed that it appears to reduce stress itself and improves focus and concentration, and builds self esteem and self confidence. HGH can also reverse the decline in memory and cognitive performance.
