Ipamorelin is a synthetic peptide that belongs to the growth hormone secretagogue (GHS) class. It is a selective growth hormone secretagogue, meaning it primarily stimulates the pituitary gland to release growth hormone (GH) without significantly increasing levels of other hormones like cortisol or prolactin, which can be a concern with some other GHS compounds. This selectivity is often cited as a key advantage of Ipamorelin.
The compound is typically administered via subcutaneous injection. Its primary mechanism involves acting on the ghrelin receptors in the pituitary gland, leading to a pulsatile release of natural growth hormone. Because it promotes the body's own production of GH, rather than directly introducing exogenous GH, Ipamorelin is sometimes considered to offer a more physiological approach to increasing GH levels.
Ipamorelin is not approved by the U.S. Food and Drug Administration (FDA) for general medical use. Its use is largely confined to research settings or, in some cases, compounded formulations used in specialized clinics, often in an off-label capacity. Due to its status as a controlled substance and unapproved drug, its availability and legal status vary significantly by region. Patients considering Ipamorelin must consult with a licensed healthcare provider to discuss its potential benefits, risks, and legal implications.

Note
Injectable peptides plus hormones can have overlapping or compounding effects that aren't always well characterized.
