human growth hormone is not only one of the most beneficial hormones our body produces, but one of the most sought after in exogenous form. in an exogenous form, human growth hormone is identical to the naturally produced hormone, and represents not only one of the most beneficial exogenous hormones but one of the most well-tolerated among men and women. its high level of toleration applies not only to medicinal use but performance enhancement as well.
function & usage:
the use of these sth somatotropic hormone compounds offers the athlete three performance-enhancing effects. sth (somatotropic hormone) has a strong anabolic effect and causes an increased protein synthesis which manifests itself in a muscular hypertrophy (enlargement of muscle cells) and in a muscular hyperplasia (increase of muscle cells.) the latter is very interesting since this increase cannot be obtained by the intake of steroids. this is probably also the reason why sth is called the strongest anabolic hormone. the second effect of sth is its pronounced influence on the burning of fat. it turns more body fat into energy leading to a drastic reduction in fat or allowing the athlete to increase his caloric intake. third, and often overlooked, is the fact that sth strengthens the connective tissue, tendons, and cartilages which could be one of the main reasons for the significant increase in strength experienced by many athletes. several bodybuilders and powerlifters report that through the simultaneous intake with steroids sth protects the athlete from injuries while inereasing his strength.
the use of human growth hormone was first successful in 1958. at this time, human growth hormone was a pituitary extract; it was directly extracted from the pituitary of human cadavers. in 1985, the u.s. fda would ban its use. extracted human growth hormone had been successful in many treatment plans, but it also proved to carry with it strong unsanitary disadvantages. in fact, pituitary human growth hormone was linked to cjd, a degenerative brain disorder that is fatal. however, very few fell prey to cdj, approximately 1% of all users, but this was enough for the fda to impose a ban.
commonly, those in the media or in any popular culture conversation refer to human growth hormone as an anabolic steroid. however, human growth hormone is in no shape or form an anabolic steroid. yes, it does carry strong anabolic properties, but being anabolic does not make something an anabolic steroid. food is also highly anabolic, but no one would call chicken or ground beef an anabolic steroid.
