MGF is produced biologically when muscle fibers are broken down through resistance (weight training). It is a potent factor in muscle growth. MGF stimulates muscle growth, creates new muscle fibers, promotes nitrogen retention and increases protein synthesis. This compound is commonly used for overall growth of muscle and to promote growth in body parts that are not up to par with the rest of the user’s physique. Results usually depend on dosage. Fat loss and strength increases are not typically seen with MGF’s use (as they are in IGF-1 use).
The PEG itself is safe for use as it is approved by the US Food and Drug Administration (FDA) and does not react in the body. The PEG is not broken down in the body and excreted (intact) through urine or feces. Any risk associated PEGylated drugs is due to drug itself not the PEG per se.
PEG-MGF, or PEGylated Mechano Growth Factor is a new and innovative form of MGF that outperforms natural MGF many times over. MGF is a splice variant of the IGF gene which increases stem cell count in the muscle and allows for muscle fibers to fuse and mature. This is a process required for growth of adult muscle. Natural MGF is made locally and does not travel into the bloodstream. Synthetic MGF is water based and when administered intramuscularly, travels into the bloodstream. MGF is only stable in the blood stream for only a few minutes.
Growth factors are a type of organic matter necessary to regulate the normal growth and metabolism of microorganisms, but cannot be synthesized by simple carbon and nitrogen sources. In addition to vitamins, growth factors in a broad sense include bases, purines, pyrimidines, biotin, and niacin, and sometimes also include amino acids required by amino acid auxotrophic mutants; while growth factors in a narrow sense generally refer to vitamins only. A class of peptides that regulate cell growth and other cell functions by binding to specific, high-affinity cell membrane receptors. It exists in platelets and various adult and embryonic tissues and most cultured cells, and has certain specificity for different types of cells. Generally, the growth of cultured cells requires the coordination of multiple growth factors. Tumor cells have the characteristics of independent growth independent of growth factors.
