1) Muscle Growth
FST344 has gained attention in the bodybuilding community due to claims that it can significantly boost muscle mass, although there are relatively few scientific studies that directly back this up in healthy human subjects.
2) Preventing Muscle Loss
Boosting FST344 levels has also been tested as a treatment for sarcopenia, an age-related muscle-wasting disease. In old mice, daily injections of epicatechin (a natural compound that increases FST344 levels) led to increased overall muscle strength. The same treatment in 6 human subjects increased their hand grip strength after seven days
3) Baldness
A small trial on 26 men with male-pattern Baldness found that a single injection of FST344 with other growth factors increased the number of hairs on the head as well as their thickness (follicle density and hair shaft thickness). These beneficial effects lasted for up to a year with only a single treatment without needing repeated administrations
4) Role in Reproductive Health
In men, seminal fluid is rich in FST344, although the levels of FST344 don't seem to be directly related to sperm count .
For women, FST344 promotes folliculogenesis, the process that prepares eggs to be released from the ovaries during ovulation.
FST344 levels are reduced during menopause but can be elevated using hormone replacement therapy
