Science
Mechanism of Action
Claimed to restore T-cell differentiation similarly to thymic hormones. Product is a hydrolysate/extract rather than a monographed API in the US.
Targets
T-cell maturation (proposed)
Studies
- Thymalin immunomodulation literature— Journal/year not available
Benefits
Historical immune-bioregulator use
Potential Side Effects
- Allergic reactions to animal protein
