Head-to-head
CJC-1295 (DAC) vs Sermorelin
Side by side from the same data: half-life, evidence tier, research amounts, common schedule, and every decay curve on one chart.
How they differ
A plain-language read of what actually sets them apart. Reference only, not medical advice.
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.
Side by side
Every figure is drawn from this site's own compound data — the same numbers on each compound's page.
| Measure | CJC-1295 (DAC) | Sermorelin |

| Typical vial | 2 / 5 mg | 5 / 9 mg |
| Research amount | 2–4 mg | 100–500 mcg |
| Common schedule | Once a week | Every day |

| Studied for | Growth-hormone release | Growth-hormone release |
These amounts and schedules are figures discussed in research and community reports, shared for learning — not a recommendation and not medical advice. A step-by-step dosing schedule exists only where a human trial backs it; the evidence tier tells you which.
Decay curves, overlaid
Every compound on one chart — something the single-compound pages cannot show.
Each line is scaled to that compound's own first dose, so the chart shows how each one builds up over time — not how the compounds' doses compare to one another, which these different molecules share no common unit for.
