Bryan Johnson's thymus rejuvenation protocol from Project Blueprint. Epithalon (10mg/day) and Thymosin Alpha-1 (1.5mg/day) injected IM for 5 consecutive days, then nothing for 6 months. Follows the Khavinson protocol. Dosing sourced from tweets; the original post had ambiguous wording that the community later resolved. Budget $100-250 per pulse cycle.
