Mechanical growth factor
Mechanical growth factor (MGF) – a substance that is produced after heavy physical exertion; is a subspecies of insulin-like growth factor (IGF1), produced in the liver. When muscle fibers are damaged as a result of the load, the receptors give a signal to stem cells. Those are activated and transfer their nuclei to muscle tissue. As a result, new myoblasts (muscle cells) are formed. In its action, it is similar to growth hormone, but, unlike it, it does not contribute to the strengthening of tissues and cartilage. Everyone knows that if a person is constrained in movement and activity, his muscles will atrophy with time. But not everyone knows that the process of atrophy is based on the lack of development of a mechanical growth factor.
The use of mechanical growth factor in bodybuilding
If you enter pure MGF, it will collapse in a few minutes. Under natural conditions, mechanical growth factor is produced in the body constantly. But if there is a need to increase its quantity, you need to think of a way to fix the substance. This method is pegylation – combining the IFC molecule with the polyethylene glycol molecule, which prevents its destruction and reduces biological activity. Therefore, at this time, all MGF preparations are pegylated – Peg-MGF. Take the drug you need two or three times a week. Due to maintaining a constant concentration of its action has a long time. Professional athletes should be aware that very soon pegylated peptides will be detected during doping tests. Moreover, the timing of determination is more than in conventional sports preparations.
MGF should be taken subcutaneously, as it is rapidly dissolved by the organs of the gastrointestinal tract when administered orally.
Although clinical studies of the effects of mechanical growth factor are still ongoing, the pharma provides it to bodybuilders for consumption. The experience obtained during the research gave the opportunity to form the scheme and the rate of admission:
Take should be 100-200 mcg with an interval of 2-4 days. Excess dose does not improve the result.
It is injected under the skin with an insulin syringe. Intramuscular injection does not have a local effect on the selected muscle group.
The course should last 35-40 days.
Store in a refrigerator at 2-8 ° C.
Implementation period: two years from the date of manufacture. The prepared solution is stored in the refrigerator for 20-30 days.
MGF positive effect
Conducting a five-week course of mechanical growth factor gives the following results:
The processes of hyperplasia (an increase in the number of muscle cells) and hypertrophy (an increase in the volume of myoblasts) occur regardless of the person’s age.
Increased delineation of the superficial vessels that protrude above the muscles.
The amount of adipose tissue decreases by an average of 5-6%.
Increased muscle relief.
These are the results that are relevant in sports. But MFR reproduces the effect on the general condition of the body:
- improved immune responses;
- acceleration of regenerative processes;
- protection of the nervous system;
- improving skin tone;
- preservation of heart function even after myocardial infarction;
- decrease in cholesterol concentration.
Clinical studies have shown such negative effects:
- itching at the injection site;
- risk of prostate cancer;
- rapid pulse;
- tingling in fingertips (rarely);
- injection swelling;
- epistaxis (not all);
- slowing the differentiation of bone marrow cells.
