Riptropin er en av flere re-branded generiske veksthormon-merker. Den selges utelukkende på det svarte markedet (mest i Storbritannia). Den er produsert av et ukjent laboratorium i Kina. Brukere rapporterer forskjellige resultater fra batch til batch, som indikerer at det kan komme fra ulike kilder. Selv om det er merket som 191 aminosyresekvensen den rapporterte å være 192 amino acid (somatrem) – not identical to human body’s own growth hormone.
Some people turn to a substance called human growth hormone (HGH) in hopes that it will keep them feeling and looking youthful. But experts say that hope is unfounded. And worse, these products can be harmful.
HGH, produced by the pituitary gland, spurs growth in children and adolescents. It also helps to regulate body composition, body fluids, muscle and bone growth, sugar and fat metabolism, and possibly heart function. Produced synthetically, HGH is the active ingredient in a number of prescription drugs and in other products available widely over the Internet.
