pdGrowth 4iu – Human Growth Hormone, HGH, GH, Somatropin is a peptide hormone that is used in sports for athletic enhancement. Growth hormone or somatropin gets its name from the fact that it causes a pronounced linear growth acceleration, mainly due to the growth of long tubular extremity bones.
Anabolic effects – causes muscle growth
Anti-catabolic effect – inhibits muscle breakdown
Decreases body fat
Regulates the use of energy
Accelerates wound healing
Has a rejuvenating effect
Stimulates the re-growth of the internal organs
Causes bone growth and increases the growth of young people up to 26 years, strengthens bones
Increases glucose levels in blood
Boosts the immune system
Some effects are caused directly by medication but a significant part of its effects causes Insulin-like growth factor (IGF-1), which is produced by the liver and stimulates the growth of most of the internal organs. Almost every effect of growth hormone in sports is associated with IGF-1.
Age-related secretion changes
The secretion of growth hormone decreases with age. It is minimal in the elderly, who have a reduced base level, and the frequency and amplitude of secretion peaks. Somatropin baseline is maximal in early childhood, the peak amplitude of secretion is maximal in adolescents during intensive linear growth and puberty.
Daily rhythms of secretion
The secretion of somatotropin occurs periodically and has several peaks throughout the day (usually secretion peak occurs every 3-5 hours). The highest peak is observed at night, about an hour after falling asleep.
HGH in bodybuilding
Use of exogenous human growth hormone (HGH), via injection, was originally for medical purposes until athletes began abusing HGH with the goal of increasing their abilities. First HGH was only available from cadavers and then recombinant human growth hormone (rHGH) was developed in 1981. In 1989 the International Olympic Committee branded human growth hormone a banned substance. Although abuse of human growth hormone for athletic purposes is illegal in many countries, over the past decade sales of HGH have increased. Athletes have been said to abuse human growth hormone, including in combination with other performance-enhancing drugs such as androgenic Anabolic steroids.
Lean muscle mass and fat burning
The main reason for the high popularity of the growth hormone in sports is the ability to reduce body fat. Also, studies have shown that it increases lean body mass. Short-term fluid retention can cause increased muscle mass. Another benefit is that HGH may promote resistance to injury or faster repair. It is because growth hormone builds up connective tissue within muscles. It should be noted that the use of growth hormone in powerlifting is pointless because no increase in muscle strength was observed. It also does not increase stamina and performance but it actually reduces fatigue threshold and delays recovery. General conclusion: HGH can be used in sports to increase lean muscles. Advantages: high effectivity, low frequency of side effects, it doesn’t affect sexual functions, doesn’t cause androgenic effects and doesn’t require PCT, after a 1-month cycle general mass increases with 3-4 kg and sometimes it doesn’t change at all.
