MK-677 dosage: 10-25 mg daily, most commonly 15-20 mg once in the evening. Beginners start 10 mg for 2 weeks, then increase to 15 mg based on tolerance. Timing: Take 30-60 minutes before bed on an empty stomach to maximize GH secretion. No tolerance develops; dose remains consistent throughout cycle.
Standard Dosage Ranges
Beginner: 10 mg daily for 2 weeks, then increase to 15 mg. This allows assessment of individual tolerance before reaching standard dose. Intermediate/experienced: 15-20 mg daily (sweet spot for most users). Advanced: 20-25 mg daily for maximum GH elevation. Higher doses (25+ mg) show diminishing returns; side effects increase without proportional benefits.
How to Determine Your Optimal Dose
Start low: 10 mg daily for 1-2 weeks. Assess side effects (appetite increase, lethargy, water retention) and training response. At week 2-3, if tolerating well and seeing benefits, increase to 15 mg. Most users find 15-20 mg optimal; increase further only if seeking maximal GH elevation and tolerating side effects. Don't exceed 25 mg for your first cycle.
Timing and Fasting
Evening administration (30-60 min before bed) aligns GH secretion with natural nighttime pulses, maximizing effect. Empty stomach critical: Food (especially protein) blunts GH secretion 30-50%. Wait 2+ hours after eating before dosing. Some users take AM dose pre-breakfast on empty stomach for additional GH pulse, but evening dose is primary.
Adjusting Dosage During Cycle
Fixed dose throughout: Most users maintain same dose (e.g., 15 mg daily) for entire cycle. Progressive increase: Some start 10 mg, increase by 5 mg every 4 weeks. Drawback: Can't isolate which dose optimizes response. Sticking with fixed dose is simpler. If side effects excessive, reduce dose rather than increase. If minimal benefits at week 4-6, increase before week 8.
Dosage Comparison: Solo vs Stacking
MK-677 solo 15 mg: Optimal for muscle gain, recovery, sleep. MK-677 15 mg + testosterone 400 mg/week: Synergistic; both at moderate-dose. MK-677 25 mg + testosterone 500+ mg/week: Maximum anabolic effect, higher side effects. GH secretagogue stacking (MK-677 + Ipamorelin): Usually keep MK-677 at 15-20 mg, add Ipamorelin 200-300 mcg 2-3x daily for amplified GH.
Dose Adjustment for Women
Women typically use 10-15 mg daily (lower than men due to lower bodyweight and different GH response). Start 10 mg, increase to 12-15 mg based on tolerance. No virilization risk at any dose. Response excellent at lower doses than men; 10 mg often produces equivalent results to men using 15-20 mg.

Q: Can I split the dose?
A: Yes, possible split 7.5 mg AM + 7.5 mg PM, but single evening dose is optimal for sleep GH benefit.
Q: What if I miss a dose?
A: No problem. Resume normal schedule next day; don't double-dose.
Q: Is higher dose better?
A: Not necessarily. 15-20 mg covers 95% of benefits; 25+ mg adds side effects with minimal benefit gain.
