Riptropin is one of several re-branded generic growth hormone brands. It is exclusively sold on the black market (mostly in the UK). It is produced by an unknown lab in China. Users report different results from batch to batch, which indicates that it might be coming from various sources. Although labelled as 191 amino acid sequence it reported to be 192 amino acid (somatrem) – not identical to human body’s own growth hormone.
Some people turn to a substance called human growth hormone (гормон роста) 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.
гормон роста, 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.
