CJC-1295 With DAC vs Without DAC: Half-Life and Research Design

### DAC chemistry **Drug Affinity Complex (DAC)** conjugation to CJC-1295 binds serum albumin, slowing clearance and extending **circulating half-life** compared with **no-DAC** CJC-1295 in pharmacokinetic studies. ### Research implications (conceptual) Longer half-life can mean fewer administrations in animal models—but also different pulse physiology vs short-acting GHRH fragments. Study design depends on endpoint: acute GH pulse vs sustained IGF-1 elevation. ### No protocols We do not provide doses or schedules. Consult the literature and institutional IACUC or equivalent oversight. ### RUO Laboratory research only. *Both CJC-1295 (no DAC) and CJC-1295 with DAC are available for research at peptide limited.*
