Synthetic analogs reproduce this signal with optimized pharmacokinetic profiles: Sermorelin (GRF 1-29): shortest active fragment, half-life ~10 minutes, signal close to natural Tesamorelin : analog stabilized by an N-terminal trans-3-hexenoyl group, half-life ~26 minutes, only molecule of the family with FDA approval (HIV-associated lipodystrophy reduction) CJC-1295 with DAC : Drug Affinity Complex modification that binds plasma albumin, extending half-life to ~8 days and creating continuous "GH bleed" rather than a pulse Key point: GHRH analogs preserve physiological pulsatility
