Description

Follistatin 344 (FS344) is a naturally occurring glycoprotein that inhibits myostatin, a protein that limits muscle growth. By blocking myostatin, FS344 promotes significant muscle hypertrophy, making it popular among athletes and bodybuilders. Additionally, it supports faster recovery from injuries, reduces inflammation, and may offer benefits in treating muscle-wasting diseases and fibrotic conditions. Typically administered via subcutaneous injection, common dosing protocols involve 100–200 mcg per day for 10–20 days, repeated every six months for sustained benefits. While generally safe when used as directed, medical supervision is recommended to avoid potential side effects such as hormonal imbalances or unregulated tissue growth .(PEN PEPTIDE, Senecabiomedical)
