Ibutamoren (MK-677) 15mg – Growth Hormone Secretagogue
Ibutamoren (MK-677) is a potent growth hormone secretagogue formulated to stimulate the pituitary gland to release growth hormone (GH). Each resealable pouch contains 60 tablets, with 15 mg of MK-677 per tablet. By mimicking the action of the hunger hormone ghrelin, Ibutamoren significantly elevates circulating levels of Growth Hormone (GH) and Insulin-Like Growth Factor 1 (IGF-1) without injections. It is commonly used to support faster recovery, deeper sleep, and muscle tissue development (muscle hyperplasia).
Product Composition
- Active Ingredient: Ibutamoren (MK-677) 15 mg per tablet
- Quantity: 60 tablets per pouch
The “Accel 15” formulation provides a flexible daily dosage option. Although it is often grouped with SARMs, MK-677 is non-hormonal and does not suppress natural testosterone production. This makes it a versatile compound that can be used year-round or as a bridge between cycles, depending on individual protocols and goals.
Key Features
- Drastically increases serum IGF-1 levels, which are crucial for muscle growth and repair.
- Supports improved sleep quality and deeper REM cycles.
- Significantly increases appetite, making it ideal for bulking phases and hard gainers.
- Helps improve skin elasticity as well as hair and nail appearance.
- May support faster healing of tendons, ligaments, and long-standing injuries.
Benefits of Ibutamoren (MK-677)
Muscle Growth
By elevating IGF-1 levels, Ibutamoren promotes nitrogen retention and helps create an anabolic environment that supports the development of new muscle tissue and overall lean mass gains when combined with appropriate training and nutrition.
Recovery & Sleep
Users frequently report deeper, more restorative sleep, which is one of the most important windows for muscle repair, nervous system recovery, and overall performance improvements.
Bulking Support
As a ghrelin mimetic, MK-677 triggers a pronounced hunger response. This can help hard gainers and those on a bulking diet consume the additional calories needed to support muscle growth and weight gain.
How to Use Ibutamoren (MK-677)
MK-677 has a long half-life of approximately 24 hours, allowing for convenient once-daily dosing.
Standard Dosage: 15 mg to 30 mg per day (1–2 tablets).
Timing: If the appetite increase is beneficial for your goals, take your dose in the morning. If you experience lethargy, many users prefer to take it in the evening or before bed.
- Cycle Duration: Unlike traditional steroids, MK-677 is typically used for longer periods (around 3–6 months) to fully benefit from sustained IGF-1 elevation.
- Stacking: Commonly stacked with SARMs (such as RAD-140) or anabolic steroids to complement their effects. It is also often used during PCT strategies to help maintain hard-earned gains.
- Side Effects: Monitor blood glucose levels, as MK-677 may slightly affect insulin sensitivity. Individual responses can vary.
Always consult a qualified healthcare professional before starting any supplement or research compound regimen. This product can significantly increase hunger and may cause initial water retention in some users.
