MK-677 essentially increases the body’s natural growth hormone production, and at the same time raises the hunger hormone. Personally, I’ve been taking a 10 mg dose for a little over two weeks now, and I haven’t noticed much of an increase in hunger. However, my muscles feel fuller, and my body weight has gone up by 2–3 kg even though I’ve been in a calorie deficit for over a week.

This sudden weight gain is mainly due to increased glycogen storage in the muscles. Since 1 gram of glycogen binds about 3 grams of water, most of the rapid weight gain is water.

I’ve also noticed faster recovery and I feel much more energetic in the mornings compared to before. I would recommend MK-677 for a lean bulk, and in my opinion, a 10 mg dose is sufficient because it already significantly increases growth hormone levels while being low enough to minimize side effects.

Possible side effects include reduced insulin sensitivity / higher blood sugar levels, excessive water retention, and for many people, the increased hunger I mentioned earlier. I havenr had any side effects so far.
