SARMS – Ibutamorin (MK-677) 15 mg

SARMS-Ibutamorin® 15 mg, also known as MK-677 (Ibutamoren), is a growth hormone secretagogue that increases the secretion of growth hormone and insulin-like growth factor-1 (IGF-1). It is commonly used to support recovery, muscle growth, and overall performance.

How it works

Ibutamorin works by binding to ghrelin receptors, which stimulates the release of growth hormone from the pituitary gland. This leads to increased IGF-1 levels, which may support muscle protein synthesis, recovery, and fat metabolism. Unlike SARMs, it does not directly interact with androgen receptors.

Proper use and dosage

Typical dosages range from 15–30 mg per day, with many users starting at 15 mg to assess tolerance. It is usually taken once daily, often before bedtime to align with natural growth hormone release during sleep. Cycle length commonly ranges from 8–12 weeks.

Benefits

Ibutamorin is associated with improved recovery, better sleep quality, increased appetite, and potential gains in lean muscle mass. It may also support overall body composition and training performance over time.

Side effects

Possible side effects include increased appetite, water retention, and potential effects on insulin sensitivity or glucose regulation. These effects are generally dose-dependent and may be managed with proper monitoring and lifestyle control.
