MK-677 (Ibutamoren) is an oral compound that mimics ghrelin to stimulate natural growth hormone (GH) release. Studied for its potential effects on body composition and recovery, this research compound offers a non-steroidal approach to GH pathway investigation.
🔬 What Is MK-677 (Ibutamoren)?
A growth hormone secretagogue that signals the body to produce more GH and IGF-1. Unlike injectable GH, MK-677:
- ✅ Taken orally with sustained activity
- ✅ Preserves natural pulsatile hormone rhythms
- ✅ Studied for muscle preservation and age-related conditions
⚙️ Research Mechanism
MK-677 activates ghrelin receptors, triggering pituitary GH release which leads to:
- Increased IGF-1 production
- Enhanced protein synthesis
- Improved cellular regeneration
- Modulated sleep architecture (particularly REM cycles)
📊 Documented Research Benefits
| Research Area | Observed Effects | Potential Applications |
|---|---|---|
| Body Composition | Increased lean mass retention | Muscle wasting studies |
| Metabolic Function | Improved nutrient partitioning | Metabolic research |
| Sleep Quality | Enhanced REM sleep duration | Sleep disorder models |
| Tissue Repair | Accelerated recovery markers | Injury recovery studies |
| Bone Density | Improved mineral retention | Osteoporosis research |
