An elevated HGH level may support new muscle tissue growth, and also enhance strength, energy levels, and connective tissues. HGH is also a potent modulator of fat loss. The physique- and performance-enhancing properties of growth hormone are widely accepted by the bodybuilding and competitive athletic communities, such that rHGH medications are very popular.
When used for physique- or performance-enhancing purposes, HGH is given by subcutaneous injection. It is typically administered at a dosage of 0.2 to 0.5 mg per day (200-500 mcg), which is given before sleep. Studies, however, do suggest that this drug is more effective when given twice daily. Therefore, it is often preferred to divide the total daily dosage into two applications,one in the morning and one in the evening.
