CJC-1295 is a long-acting synthetic analog of growth hormone-releasing hormone (GHRH). Unlike natural GHRH which degrades in minutes, CJC-1295 is engineered to remain active in the bloodstream for days, enabling infrequent dosing with sustained GH elevation.
CJC-1295 binds to albumin in the bloodstream via drug affinity complex (DAC) technology, dramatically extending its half-life to 6–8 days. It consistently elevates GH and IGF-1 levels, and is most commonly combined with Ipamorelin to create synergistic, amplified GH pulses.
The CJC-1295/Ipamorelin combination is one of the most popular peptide stacks. Users report improved sleep depth and quality within weeks, followed by gradual improvements in body composition, skin texture, energy, and recovery over 3–6 months.
