A specific class of short-chain amino acid compounds utilized in clinical practice to precisely modulate the endocrine system, primarily aiming to optimize the ratio of lean muscle mass to adipose tissue. These peptides function as secretagogues, safely stimulating the body’s endogenous production of key anabolic hormones, notably Growth Hormone. The therapeutic objective is to enhance muscle protein synthesis and promote lipolysis, leading to favorable body recomposition, improved metabolic health, and enhanced physical structure.
Origin
The term stems from the clinical goal of “Body Recomposition,” the process of increasing lean mass while decreasing fat mass, and “Peptides,” the biochemical class of molecules. These compounds are synthetic analogs of naturally occurring gut or hypothalamic hormones, developed through advancements in peptide chemistry and endocrinology since the mid-20th century. Their application in wellness is a direct extension of their initial use in treating clinical hormone deficiency states.
Mechanism
The primary mechanism involves stimulating the pituitary gland to release Growth Hormone (GH) in a pulsatile, physiological manner, closely mimicking the body’s natural rhythm. Growth Hormone Releasing Hormones (GHRHs) and Ghrelin mimetics act on distinct pituitary receptors to amplify the somatotropic axis signaling. This enhanced GH pulse then drives the liver’s production of Insulin-like Growth Factor 1 (IGF-1), which is the key mediator of the anabolic and lipolytic effects necessary for positive body recomposition.
