- Sermorelin Acetate
- GHRH receptor agonist. Stimulates endogenous GH pulse
- 250–300 mcg nightly before bed
- 30–50% elevation at 8–12 weeks
- Minimal. Occasional injection site irritation, transient flushing in first week
- Sustainable, slower results; best for long-term protocols without appetite disruption
- Ipamorelin
- Ghrelin receptor agonist. Triggers GH release via ghrelin pathway
- 200–300 mcg 1–2× daily
- 40–60% elevation at 8 weeks
- Low. No cortisol or prolactin spike
- Comparable efficacy to sermorelin but requires multiple daily doses for sustained effect
- CJC-1295 (DAC)
- Modified GHRH analogue with extended half-life (6–8 days)
- 1–2 mg weekly subcutaneous
- 50–80% elevation sustained across injection interval
- Moderate. Reported GH bleed (elevated baseline GH disrupts pulsatility)
- More potent but risks flattening natural GH rhythm; less popular in 2026 logs
- MK-677 (Ibutamoren)
- Oral ghrelin mimetic. Non-peptide secretagogue
- 12.5–25 mg daily oral
- 60–90% elevation within 4 weeks
- High. Increased appetite, water retention, potential insulin resistance with chronic use
- Fastest IGF-1 elevation but side effect profile limits long-term viability
