MK-677 (Ibutamoren): Muscle Growth, Fat Loss & Recovery in One Powerful Peptide
Looking to build lean muscle, shred fat, and recover faster — without shutting down your testosterone?
MK-677 might be your game-changing solution.
What is MK-677?
MK-677, also known as Ibutamoren, is an oral growth hormone secretagogue. That means it signals your body to naturally produce more growth hormone (GH) and IGF-1 — two key hormones for muscle growth, recovery, and fat metabolism.
Unlike injectable HGH, MK-677 works with your body’s endocrine system. It binds to ghrelin receptors in the brain (specifically the hypothalamus and pituitary gland), triggering a natural cascade of growth hormone pulses.
How MK-677 Works
Mimics ghrelin (a hormone released after eating)
Binds to GHSR (ghrelin receptors) in the hypothalamus
Increases natural growth hormone and IGF-1 secretion
Activates anabolic pathways (like PI3K/AKT/mTOR)
Enhances fat burning, muscle repair, and recovery
MK-677 preserves your body's hormonal feedback loop, meaning no testosterone shutdown and no injections required.
MK-677 Benefits
1. Boosts Lean Muscle Mass
Promotes muscle fiber growth via elevated GH + IGF-1
May suppress myostatin, unlocking more muscle potential
Supports strength gains and recovery from training
2. Enhances Fat Loss
Increases lipolysis (fat breakdown)
Improves metabolic rate while preserving lean mass
Ideal for recomp or cutting phases
3. Accelerates Recovery
Improves muscle + joint repair post-workout
Supports tendon and ligament healing
Enhances deep sleep quality (where GH release peaks)
4. Improves Bone Density
Stimulates osteoblast activity (bone-building cells)
Supports long-term bone health, especially for aging or injured athletes
5. Anti-Aging & Vitality
Reverses GH decline with age
Improves skin elasticity, energy, sleep, and cognitive clarity
Popular with biohackers for hormone optimization
MK-677 Dosage & Cycle Protocol
Typical Dose: 10–25mg per day
Cycle Length: 8–12 weeks
Best Time to Take: Before bed (to synergize with sleep-based GH pulses)
MK-677 has a long half-life (~24 hours), so once-daily dosing is sufficient.
MK-677 Side Effects
While generally well-tolerated, here are a few things to monitor:
Increased appetite (very common)
Water retention (temporary, especially at higher doses)
Lethargy or fatigue (may resolve with adaptation)
Elevated blood sugar or insulin resistance (caution if diabetic)
💡 Pro Tip: Start at the low end (10mg/day) and ramp up to assess tolerance.
