TB-500 · dosing reference

What dose information exists for TB-500?

The published human dose picture for the TB-500 fragment specifically is effectively empty: the wound-healing literature concerns full-length thymosin β4, a different molecule. Compound-specific confusion is the story here.

Community-reported ranges

Community

What people report discussing or doing in forums, on Reddit and in videos. Included only to show demand and reported practice — never as clinical evidence.

Community reportedhigh discussion volume

Posts typically discuss roughly 2.0–2.5 mg twice weekly, a range traced in most cases to full-length thymosin β4 animal work rather than the fragment

The fragment (LKKTETQ) and the 43-residue parent molecule have different masses; community ranges almost never specify which substance they refer to.

Community reports describe what people say they are doing. They are not equivalent to clinical evidence, and discussion volume says nothing about whether a practice is safe, effective or even real.

Why community reports are shown at all

People search for dose information before they search for anything else in this sector. Where discussion is widespread, pretending it does not exist helps nobody. Therapept reports the discussion — its rough shape, how common it is, and where it happens — while keeping it visibly separate from every other kind of source. Community reports describe what people say they are doing. They are not equivalent to clinical evidence.
