CJC-1295 No DAC Natural GH Augmentation: Protocol Comparison
Research labs approach GH secretagogue studies with different endpoints. Some measure acute GH response, others track IGF-1 changes over weeks, and some compare pulsatile vs sustained GHRH exposure. The table below compares three common CJC-1295 protocols base

- Research labs approach GH secretagogue studies with different endpoints. Some measure acute GH response, others track IGF-1 changes over weeks, and some compare pulsatile vs sustained GHRH exposure. The table below compares three common CJC-1295 protocols based on dosing frequency, expected GH pulse characteristics, and suitability for different study designs.
- | Protocol Type | Dose Per Injection | Frequency | Expected GH Peak Timing | Baseline GH Preservation | Best Application | Professional Assessment ||—|—|—|—|—|—|| Acute Pulsatile (No DAC) | 100–200 mcg | 1–3× daily | 30–60 min post-injection | Fully preserved. Natural rhythm intact | Studies measuring endogenous GH response, receptor sensitivity research, circadian GH pattern analysis | Gold standard for natural GH augmentation. Preserves feedback loops and allows measurement of body's intact regulatory capacity || Sustained-Release (With DAC) | 1–2 mg | 1–2× weekly | Sustained elevation for 6–8 days | Suppressed after 14 days. GHRH receptor downregulation occurs | Long-term IGF-1 studies, convenience-prioritized protocols, pharmacokinetic research | Effective for sustained IGF-1 elevation but eliminates natural GH pulsatility. Not suitable for studies requiring preserved endogenous secretion || Combination (No DAC + GHRP) | 100 mcg CJC + 100 mcg GHRP-6 | 2–3× daily | Synergistic peak
- The bottom line: if your research question involves how the body regulates GH secretion endogenously, CJC-1295 no DAC is the only option that preserves that regulatory capacity. Sustained-release formulations are pharmacologically convenient but biologically disruptive to the exact mechanisms most GH studies aim to measure.
