Peptide
Thymus Extract
SaveA preparation of polypeptides and thymic hormones (thymosin, thymulin, thymopoietin) derived from calf thymus gland, used historically for immune support.
Quick verdict
Used in complementary medicine for decades. Some clinical data for immune support in hepatitis B and cancer adjunctive therapy. Product standardization is poor.
Evidence score
A rough internal score reflecting quantity, quality, and consistency of human evidence. Not a clinical recommendation.
What the research shows
Cochrane review for hepatitis B adjunct therapy found some benefit. Variable product quality makes interpretation difficult. Several European countries have used thymic extracts clinically.
Benefits
- Some Cochrane evidence for hepatitis B adjunct therapy
- Historical immune-support use in European medicine
- Multiple thymic peptides with distinct immunomodulatory roles
Dosage notes
Highly variable by product. Oral: 100–500 mg/day. Injectable: per clinical protocol.
Side effects
- Allergic reactions
- Injection-site reactions
- GI discomfort with oral forms
Who should be cautious
Animal-derived product with theoretical prion and infection risk. Product standardization varies enormously.
