What is the Origin of Endogenous Anabolics?

The term is derived from the Greek roots endo- meaning within, and anabole meaning a raising up or building up, reflecting the intrinsic nature of these tissue-building compounds. The concept originates in classical endocrinology, specifically the study of gonadal and pituitary hormones and their role in pubertal development and muscle accretion. It defines the body's internal, genetically programmed capacity for regenerative metabolism.

What is the Mechanism of Endogenous Anabolics?

Endogenous anabolics exert their effects by binding to specific intracellular or cell-surface receptors on target tissues, such as muscle and bone cells. For example, steroid anabolics like testosterone bind to the androgen receptor, directly modulating gene transcription to increase protein synthesis and decrease protein breakdown. Peptide anabolics, like growth hormone, stimulate the release of downstream mediators, notably IGF-I, which collectively drive cellular proliferation, differentiation, and tissue hypertrophy.

Endogenous Anabolics

Meaning

Endogenous anabolics are the naturally occurring hormones and signaling molecules produced within the human body that promote anabolism, the metabolic process responsible for building and repairing tissues. These compounds are essential for growth, maintenance of lean body mass, bone density, and recovery from physical stress. Key examples include testosterone, growth hormone, and insulin-like growth factor I, all of which are vital for sustained hormonal health and longevity.
