Thymalin
Longevity · Thymic peptide bioregulator
Tier C+
Bottom line
Read Off Label grades Thymalin as C+ (5.3/10) based on preclinical evidence, variable benefit magnitude, and a low-risk safety profile.
Khavinson peptide bioregulator — used in Russia for decades in elderly immunocompromised patients.
Studied, labeled, or reported-use context: 5-10 mg IM/SC daily for 5-10 day courses; repeated 1-2x/year — Research chemical; not individualized guidance.
What the evidence says
Khavinson peptide bioregulator — used in Russia for decades in elderly immunocompromised patients. Khavinson cohort data claims mortality reduction but not independently replicated. FDA status: not approved for human use.
Mechanism
Complex of thymus-derived peptides; T-cell maturation/differentiation; reduces immunosenescence; proposed restoration of thymic function
Studied, labeled, or reported dose & route
5-10 mg IM/SC daily for 5-10 day courses; repeated 1-2x/year
This records doses and routes described in studies, approved labeling, clinical practice, or documented use. It is not individualized guidance and does not establish safety; context changes with indication, formulation, health history, monitoring, and other medicines.
