About:
A thymus-derived peptide preparation from Russian research, studied for immune effects in older adults.
What does this peptide do?
Backed by human trial data, narrower than the strongest evidence. Research focuses on immune function.

Immune function
Russian research studied immune effects in older adults.
Evidence grade
BHighest evidence grade among the graded claims: B. Grades reflect study strength, not benefit.
What are the benefits and side effects of this peptide
What research says it may help with
- Thymalin comes from one Russian research programme, where a controlled study of thymus and pineal preparations reported effects on survival measures in older people.
- No independent replication outside that programme was verified, and modern safety and dosing data are absent.
Who should avoid it
- People who are pregnant or breastfeeding
- Children and adolescents
- People taking immunosuppressive medication
- Known hypersensitivity to peptide preparations
See the safety section. Absence of a flag is not evidence of safety.
A grade reflects evidence strength, not a recommendation to use this compound; a strong grade can attach to a harmful effect.
