- Sermorelin and CJC-1295 without DAC produce qualitatively similar GH release patterns: a brief, sharp pulse following each injection that mirrors the body's natural GHRH-driven GH release. Somatostatin tone rises in response, the pulse terminates, and the system resets for the next injection. This pulsatility is biologically similar to what the pituitary does on its own, and it preserves the feedback loop intact.
- CJC-1295 with DAC produces a fundamentally different pattern. By maintaining continuous GHRH receptor occupancy for days, it creates a persistent GH secretory drive that is modulated by somatostatin but never fully interrupted. The resulting GH and IGF-1 elevation is more sustained and more tonic. Whether continuous elevation or pulsatile release is more beneficial for a given application depends on the specific goal: sustained elevation may be preferable for maximizing IGF-1 trophic effects; pulsatile release is more physiologically authentic and better aligned with the axis-preservation advantage of GHRH analogs.
