Immune regulator from thymus.
Mechanism of Action
Enhances T-cell production and vaccine response.
Key Benefits
- Infection resistance
- Vaccine adjuvant
Common Uses
What to Expect
Onset
Immune effects build over 1–2 weeks; not an immediate subjective 'feeling'
Duration
Effects persist for weeks to months after completing a cycle; immune memory is long-lasting
What Users Report
- A sense of immune resilience — going through cold and flu season without getting sick
- Faster recovery from illness when taken at the first signs of infection
- Effects are generally subtle rather than dramatic — this is an immune modulator, not a stimulant
- Some users report improved energy levels and reduced low-grade inflammation
- Best appreciated when you're exposed to illness and don't get sick, or recover much faster than usual
- Enhanced vaccine response — some use it around vaccination schedules for better antibody production
- Overall feeling of being more robust and resilient, especially during seasonal changes
Typical Timeline
Weeks 1–2: Immune system activation begins; no dramatic subjective changes. Weeks 2–4: Improved immune resilience becomes noticeable during exposure to illness. Weeks 4–8: Full cycle; enhanced T-cell function and infection resistance. Post-cycle: Benefits persist for months as immune memory is established.
Side Effects
- Minimal
Dosage Protocol
1.6 mg subcutaneously 2x/week. Cycles: 4–8 weeks; for immune boost, daily 450–900 mcg.
