What half-life means for Sermorelin
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 Sermorelin, the characterised half-life is ~11–12 minutes. This directly informs the typical protocol of 200–500 mcg subcutaneous at bedtime.
