Follistatin

Limited safety

Evidence

Evidence ScoreNot scored

Studies: 6

Dosage & timing

Dosage:

No legitimate or recommended dose — follistatin is not an approved medicine or a regulated supplement, and there is no controlled human dosing data for injectable recombinant follistatin. We do NOT provide a dosing protocol. The human evidence comes from localized follistatin GENE therapy delivered under research protocols (intramuscular AAV), which has no bearing on a dose for self-injected peptide.

Best Time:

Any time

Can take on empty stomach

Form:

None — unapproved grey-market research chemical
