MK-677 Benefits
- ✓Oral GH secretagogue, 24-hour GH elevation, increases IGF-1, improves sleep quality, increases lean mass, does not suppress natural GH
Statherin Benefits
- ✓enamel pellicle stabilization
- ✓calcium phosphate homeostasis
- ✓remineralization support
- ✓anti-adhesion
MK-677 Dosing
10-25 mg orally once daily before bedtime. 25 mg is the most studied dose. Can be used long-term without cycling.
Statherin Dosing
topical peptide exposure in vitro or ex vivo|salivary-mimetic coating studies|surface-conditioning protocols
MK-677 Side Effects
- ⚠Increased appetite, mild water retention, drowsiness, transient numbness, mild increase in fasting blood glucose with long-term use.
Statherin Side Effects
- ⚠minimal systemic effects expected
- ⚠surface adsorption variability
- ⚠rapid enzymatic breakdown
Research Overview
MK-677
A landmark 2-year study in elderly adults demonstrated significant increases in lean mass, GH pulsatility, and IGF-1 to youthful ranges. Selectively agonizes GHS-R1a without increasing cortisol or prolactin.
Statherin
Statherin has been extensively studied as a key regulator of enamel mineral equilibrium and pellicle biology. It is used in biomimetic dentistry research to model or improve enamel protection and remineralization.
