One older human pharmacology paper on melanocortin receptor agonists reported nausea and yawning as frequent side effects with Melanotan II in a sexual-function research context (PubMed)
Research context Ipamorelin (NNC 26-0161) is a synthetic, C-terminally amidated pentapeptide growth-hormone secretagogue that acts through the ghrelin/growth-hormone secretagogue receptor
For example, variants that include added drugs like phentermine are more likely to cause side effects than variants that strictly use natural vitamins and minerals
Eat slowly and chew thoroughly: Research found that chewing each bite 30 times was associated with higher GLP-1 concentrations
Possible side effects include fatigue, headaches, or stomach discomfort. If side effects occur, reduce use or discontinue use entirely
