Immune Support
Research compounds studied for adaptive immunity modulation, antimicrobial defense, thymic function, and systemic inflammation reduction.
Most researched for Immune Support
Thymosin Alpha-1
The most clinically validated immune peptide in this category - used as an approved pharmaceutical in over 35 countries for hepatitis B, hepatitis C, and immunocompromised patients. Activates T-cell maturation and dendritic cell function to enhance adaptive immunity. The extensive clinical database and pharmaceutical track record make it the most evidence-based starting point in this category.

Example stacks
Immune Support - Beginner
Thymosin Alpha-1 is the most clinically validated immune peptide - used as a pharmaceutical in 35+ countries.
- • Space injections evenly - e.g. Monday and Thursday
- • Run the full 4-6 week cycle
- • Combine with adequate sleep, vitamin D, and zinc
Immune Support - Intermediate
TA-1 modulates adaptive immunity while BPC-157 reduces systemic inflammation that suppresses immune function.
- • Take BPC-157 orally if gut inflammation is a contributing factor
- • Run the full 6-week cycle even after symptoms improve
- • Track recovery speed from minor illnesses
