Acute studies only; long-term unknown

Short studies report no serious side effects. But hexarelin is not selective. It raises cortisol and prolactin along with growth hormone. The authors of the comparison study called out this lack of specificity directly. No one has studied long-term use in humans. So the effects on glucose tolerance, blood pressure and tumour growth are unknown. Research-chemical products are not tested for purity or sterility. 23
