Overview
Thymosin Alpha-1 is a thymus-derived peptide that modulates T-cell function and immune responses — it’s actually an approved drug for hepatitis B and C in some countries. Research protocols use it for immune support and recovery.
Preparation
Reconstitute a 5 mg vial with 3 mL of bacteriostatic water (BAC) for a ~1.67 mg/mL concentration. Refrigerate after mixing.

Protocol
| Period | Dose | Units (@ 1.67 mg/mL) | Frequency |

| Weeks 2–8 | 500 mcg (0.5 mg) | 30 units (0.30 mL) | 1x/day |
Cycle
8-week daily cycles, 1–2 cycles per year. Clinical schedules also use 2x/week maintenance after a loading phase.
