What half-life means for Melanotan II
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 Melanotan II, the characterised half-life is ~33 hours. This directly informs the typical protocol of 100 mcg daily loading, 250–500 mcg maintenance.
