MK-677 (Ibutamoren) by Dragon Pharma is a potent, orally active growth hormone secretagogue that mimics ghrelin and stimulates natural GH and IGF-1 production. Supplied in 25 mg tablets, this non-peptide compound is widely researched for promoting lean body mass, enhancing recovery, and potentially supporting anti-aging interventions. Unlike peptides, MK-677 can be taken orally without degradation in the GI tract.
Mechanism of Action
MK-677 binds to ghrelin receptors in the hypothalamus and pituitary, promoting the secretion of growth hormone (GH) and subsequently increasing circulating IGF-1 levels. It acts without suppressing endogenous testosterone or requiring injections, making it a versatile research candidate.
This compound has shown promise in studies targeting age-related muscle loss, GH deficiency, recovery enhancement, and improved sleep quality. It may also stimulate appetite, which is relevant in metabolic or wasting disorders.
Key Features & Benefits
- Boosts GH & IGF-1: Promotes sustained elevations in growth hormone and IGF-1 without daily injections.
- Supports Muscle Retention: Researched for preventing lean mass decline in older or calorie-restricted subjects.
- Non-Peptide Oral Secretagogue: Easy oral administration with high bioavailability.
- Recovery & Sleep Aid: Shown in studies to improve REM sleep quality and muscle repair efficiency.
- No Testosterone Suppression: Unlike traditional anabolic agents, MK-677 typically does not impact natural testosterone levels in research models.

Frequently Asked Questions
It stimulates the release of growth hormone and IGF-1, potentially supporting lean mass retention, recovery, and improved sleep in research models.
Current studies indicate it does not suppress endogenous testosterone production, making it distinct from anabolic steroids and SARMs.
There is no conclusive evidence in controlled trials that MK-677 causes heart failure, but fluid retention and increased appetite have been observed in certain cases, warranting cautious use in cardiovascular models.
Unlike alkylated oral steroids, MK-677 is not hepatotoxic in research settings, though long-term hepatic impact has not been fully explored.
