Why is ipamorelin considered the safest growth hormone secretagogue?
Ipamorelin is considered the safest GH secretagogue because it selectively stimulates growth hormone release without significantly raising cortisol, prolactin, or other hormones. A 1999 study in the European Journal of Endocrinology confirmed its selectivity compared to GHRP-2 and GHRP-6.
