MK-677, also known as Ibutamoren, is a non-peptide growth hormone secretagogue. It stimulates the release of growth hormone and increases IGF-1 levels by activating ghrelin receptors, leading to faster muscle growth, enhanced recovery, and improved sleep quality.

Core Labs MK677 supports natural growth hormone production and IGF-1 levels, promotes muscle hypertrophy and fat metabolism, accelerates recovery from training, improves sleep quality, and supports lean body composition. It contains 30mg of Ibutamoren per capsule for a high-potency effect.

Take one capsule (30mg) daily, preferably in the evening before bed. MK-677 cycles typically run 8–16 weeks. Always consult a healthcare professional before starting, as higher doses and longer cycles should be carefully managed.
