The most popular GHSs for bodybuilding include: growth-hormone releasing hormones,such as sermorelin, tesamorelin, CJC-1293, and CJC-1295 ghrelin and compounds mimicking its actions,such as lenomorelin, anamorelin, ipamorelin, macimorelin, and tabimorelin growth hormone-releasing peptides (GHRPs), such as alexamorelin, GHRP-1, GHRP-2, GHRP-3, GHRP-4, GHRP-5, GHRP-6, and hexarelin Each of these peptides may stimulate the production and release of HGH, although they do so in slightly different ways
