Compound brief
Thymulin
Evidence brief. Not treatment advice or a safety clearance. Last evidence update: September 2026.
What researchers are studying it for
A nine-residue thymic peptide whose shape depends on zinc. It is smaller than thymosin alpha-1 and unrelated to thymosin beta-4.
Zinc discussion in forums is about this conformation. It is not a zinc supplement and not thymosin alpha-1.
Pathway
The nonapeptide folds around zinc. Without that ion the shape associated with thymic activity is lost.
The T-cell note is the same family as thymosin alpha-1 only in the sense that both are thymic. The sequences are not the same.
