Ipamorelin is a fascinating new muscle building discovery that is getting a lot of attention in the bodybuilding world. It is a synthetic peptide that has powerful Growth Hormone releasing properties. And these GH releasing properties are what is of interest to athletes and bodybuilders since they can make a tremendous difference in the amount of muscle you can grow and how quickly you burn fat. Ipamorelin is a penta-peptide. (Aib-His-D-2-Nal-D- Phe-Lys-NH2) And, the strength it displays may very well make regular old Growth Hormone (GH) obsolete.Ipamorelin in theory may increase Acetylchloine or Cortisol when used in higher dosages. However, and increase in Acetylchloine or Cortisol is even more likely with GHRP-2 and GHRP-6. In fact, in the case of Ipamorelin, there was little to no rise in Acetylcholine and Cortisol blood plasma levels even at injections more than 200 times higher than the effective dosage for comparable GH release.
