Peptides
Thymulin: immune-signaling research and the human evidence gap
What is it?
Thymulin is a thymus-associated peptide involved in immune regulation; it is distinct from thymosin alpha-1 and thymogen despite similar names. Mechanistic and animal findings motivate research but do not establish a safe “immune boost.” [1]
What do studies show?
In a mouse model of experimental autoimmune encephalomyelitis, investigators gave thymulin repeatedly and observed reduced disease severity and changes in inflammatory markers versus untreated animals. Mice with experimentally induced disease are not a demonstration that a catalog vial prevents infections, treats multiple sclerosis, or lowers inflammation in healthy adults. [1]
Safety
Human risks depend on exact peptide identity, formulation, route, and condition. In immune or autoimmune disease, a poorly understood intervention can be especially consequential. The study does not provide clinical safety monitoring data for self-use.

EVIDENCE CONTEXT
Why?
The cited evidence does not establish a dose for this use or product.
The mouse study used 15 micrograms per 100 g body weight intraperitoneally every other day for 30 days. This is an animal experimental exposure and cannot be presented as a human dose. No safe/effective adult immune-support dose or clearly attributable exact-product anecdotal protocol was identified. [1]
