Follistatin 344 half-life
Follistatin 344's half-life hasn't been established in humans. Estimates put it in the range of hours, but any specific number should be treated as approximate.
What a half-life actually means
A half-life is the time it takes for half of what is in your blood to be gone. It does not mean the compound is finished at that point. Half goes, then half of what is left goes, and so on.
That is why the last traces take so much longer to disappear than the first. Most references treat something as effectively cleared after about five half-lives.
Why the timing matters
A short half-life means levels swing between doses, so timing and frequency do most of the work. A long half-life means levels build for days or weeks before they settle, so a change you make today might not show up for a while, and stopping does not clear things straight away.
Follistatin 344 does not reduce to a single figure, so there is no clearance table to read off. What the paragraph above describes is the honest version: where the number comes from, and what it does and does not cover.
