Ibutamoren (MK-677) is an oral growth hormone secretagogue that increases growth hormone (GH) and IGF-1 levels by mimicking the action of ghrelin. It is commonly used to support recovery, sleep quality, and overall anabolic environment, making it especially useful during periods of intense training, caloric restriction, or when aiming to improve body composition.

This product may help improve recovery and training readiness by supporting deeper sleep and tissue repair processes. Many users report increased appetite and improved wellbeing, which can be beneficial for gaining quality mass when paired with proper nutrition. Additionally, by supporting GH/IGF-1 signaling, it may aid in muscle retention during cutting phases and contribute to a fuller, more “recovered” look over time.

Capsule content: 10 mg.

Recommended dosage: most often start with 10 mg per day (1 capsule) and assess tolerance for 7–14 days. If the goal is a more pronounced effect on markers/sleep/appetite and tolerance is good, some increase to 20 mg (2 capsules).

Maximum dosage: in practical regimens it usually does not go beyond 25 mg/day, because higher doses often increase side effects (appetite/edema/lethargy) more than benefits.

When to take:

In the evening — a popular option if sleep and recovery are the priority.
In the morning — sometimes chosen if evening use makes falling asleep harder or increases evening appetite too much.

Duration of use: minimally, it makes sense to evaluate the effect over 4 weeks. Longer cycles are used in practice, but with long-term use it is especially important to monitor well-being and metabolic markers.

Possible side effects:

Water retention and bloating, especially in the first few weeks.
Joint pain or discomfort, particularly in individuals prone to joint issues.
Numbness or tingling in extremities, which can occur when GH activity rises noticeably.
Fatigue or drowsiness, sometimes linked to changes in sleep.

These side effects are usually mild and tend to subside over time as the body adjusts.
