Overview
Follistatin 344 is a synthetic version of the naturally occurring follistatin glycoprotein, characterized by its high cysteine content and 344-amino acid precursor structure. It primarily functions as a potent myostatin inhibitor, effectively removing the biological 'brakes' that prevent muscle tissue from growing beyond certain limits. Originally discovered for its role in the pituitary gland, this glycoprotein has become a major point of interest for its ability to drastically shift the body's anabolic environment toward muscle hypertrophy.
In addition to its muscle-building properties, Follistatin 344 influences hormonal pathways by suppressing follicle-stimulating hormone (FSH) through activin inhibition. While research is largely concentrated in animal models, it is frequently studied for its potential to combat muscle-wasting conditions, improve bone density, and enhance overall physical performance. However, due to its specialized nature and the limited number of human clinical trials, it is primarily categorized as a research compound rather than a standard therapeutic agent.
Mechanism of action
FST-344 acts as an autocrine glycoprotein that binds to and neutralizes myostatin, a protein that restricts muscle growth, while also inhibiting activin to lower FSH levels.
Reported benefits
- ▸Significant acceleration of lean muscle mass development
- ▸Enhanced physical endurance and stamina
- ▸Greater bone mineral density for skeletal strength
- ▸Improved fat metabolism and reduction in body fat percentage
Reported side effects
- ·Weakening of tendons and ligaments due to rapid muscle growth
- ·Elevation of body temperature (fever-like symptoms)
- ·Localized skin irritation or redness at the injection site
- ·Potential fluctuations in reproductive hormones
