Overview
Binds to TGF-β receptors on fibroblasts, reducing myofibroblast differentiation and promoting organized ECM deposition.
Proposed mechanism
Tetrapeptide-28 is a synthetic heptapeptide that mimics TGF-β1's anti-fibrotic activity, promoting organized (not scar) collagen alignment.
What the evidence supports
Evidence rests primarily on self-reported experience. Controlled studies are lacking.
Graded Anecdotal
Case reports, clinician notes, and user-reported outcomes. Recorded for completeness and labelled plainly so it is never mistaken for data.
