Class & Mechanism — MGF, or Mechano Growth Factor, is a splice variant of IGF-1 known as IGF-1Ec. It is involved in the process of muscle hypertrophy and satellite cell activation in response to mechanical stress or muscle damage. MGF acts by binding to the type 1 IGF receptor, promoting muscle cell growth and repair through the activation of the PI3K/Akt signaling pathway [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50].
Research-documented benefits — Local corpus: silent.
General-knowledge benefits — MGF is known to play a role in muscle growth and repair, particularly in response to resistance training or muscle injury. It is being studied for its potential to enhance muscle recovery and growth in various conditions, including muscle wasting disorders.
Typical injectable protocol — Research-only; typical experimental doses are not well-established but are presumed to be in the range of 50-150 μg/kg, administered subcutaneously or intramuscularly, with frequency varying depending on the study design.
Key risks / contraindications — Potential risks include the promotion of abnormal cell growth. Contraindicated in individuals with diabetes, cardiovascular disease, or a history of cancer.
Bottom line — MGF is an experimental growth factor used in research to study its effects on muscle growth, repair, and the potential treatment of muscle wasting disorders.
