What half-life means for hCG
Half-life is the time it takes for half the compound to be cleared from the body. Shorter half-lives (< 4h) usually require daily or multiple-daily dosing to maintain levels; longer half-lives (days) support once-weekly protocols.
For hCG, the characterised half-life is ~36 hours. This directly informs the typical protocol of 250–500 IU 2–3x per week (TRT adjunct).
