Question 1

What is the difference between CJC-1295 (with DAC) and CJC-1295 (no DAC) / Mod GRF 1-29?

Accepted Answer

CJC-1295 (with DAC) is a Growth Hormone Secretagogue compound (Subcutaneous route) — GHRH analog with Drug Affinity Complex — albumin binding extends half-life to ~1 week. CJC-1295 (no DAC) / Mod GRF 1-29 is a Growth Hormone Secretagogue compound (Subcutaneous route) — GHRH analog without albumin binding. Very short half-life — preserves the natural GH pulse pattern. All are research-use-only reference compounds, not for human use.

Question 2

Which has a longer half-life, CJC-1295 (with DAC) or CJC-1295 (no DAC) / Mod GRF 1-29?

Accepted Answer

CJC-1295 (with DAC) has the longest published plasma half-life (~7.0 days (168 h)), compared with CJC-1295 (no DAC) / Mod GRF 1-29 (~30 min).

Question 3

How often is each compound dosed in the research literature?

Accepted Answer

CJC-1295 (with DAC): once weekly at a published dose range of 1–2 mg; CJC-1295 (no DAC) / Mod GRF 1-29: three times daily at a published dose range of 0.1–0.2 mg. These are descriptive reference parameters, not dosing recommendations.

Question 4
