What is hexarelin and how does it work?

Growth hormone is a natural peptide hormone from your pituitary gland. In young children, it stimulates growth. In adults, it supports muscle mass, fat metabolism, bone health, and heart health. It typically increases during deep sleep in the middle of the night. Also, its levels decline with age, contributing to age-related body fat gain, loss of lean mass, and slowed metabolism.

Growth hormone also stimulates IGF-1, which manages the effects of growth hormones. Both hormones work together on tissue and bone growth. IGF-1 weakly binds to insulin receptors and may enhance insulin action. In adults, IGF-1 also protects the blood vessels and neurons, making it important for cardiovascular, and cognitive and mental health.

Hexarelin is a synthetic growth hormone-releasing peptide that stimulates GHRH release. It’s the strongest one that also increases cortisol and prolactin. However, it does not increase appetite, making it a helpful peptide for fat loss.
