CJC-1295 (DAC) vs Sermorelin

Compare the research, key figures and safety notes.

How they differ

Both nudge the body to release its own growth hormone the same way, but they last very different amounts of time. Sermorelin is gone in about ten minutes, so it's taken nightly as a quick pulse. CJC-1295 with DAC grabs onto a blood protein and lasts about a week, so it's taken weekly and holds a steady level. Both have been tested in people — sermorelin was once a licensed product, and the DAC form comes from a step-up dosing study.
