Compound Profiles
MK-677
Ghrelin Receptor Agonist | Oral Growth Hormone Secretagogue
Selectively binds GHS-R1a receptors in hypothalamus and pituitary, triggering pulsatile growth hormone release while maintaining natural circadian patterns..
YK-11
Myostatin Inhibitor & SARM Hybrid | Experimental
YK-11 exerts its effects through two distinct but complementary pathways. First, it acts as a partial agonist of the androgen receptor (AR).

Frequently Asked Questions
Can I take MK-677 with YK-11?
Yes, MK-677 and YK-11 can generally be taken together. MK-677 (Ibutamoren) is frequently combined with YK-11. MK-677 increases growth hormone and IGF-1 through ghrelin receptor agonism, which complements YK-11's AR-mediated and follistatin-mediated anabolic mechanisms through a completely independent pathway. MK-677 does not suppress testosterone and is not hepatotoxic, making it one of the safer adjuncts to a YK-11 cycle. The combination may enhance lean mass gains, recovery, and joint comfort (via GH-mediated collagen synthesis), potentially offsetting YK-11's reported joint dryness.
Is MK-677 and YK-11 safe together?
Based on documented research, this combination is considered synergistic. However, shared safety flags include: blood pressure raising, carcinogenic risk, hepatotoxic, teratogenic. Monitor accordingly.
What are the interactions between MK-677 and YK-11?
MK-677 (Ibutamoren) is frequently combined with YK-11. MK-677 increases growth hormone and IGF-1 through ghrelin receptor agonism, which complements YK-11's AR-mediated and follistatin-mediated anabolic mechanisms through a completely independent pathway. MK-677 does not suppress testosterone and is not hepatotoxic, making it one of the safer adjuncts to a YK-11 cycle. The combination may enhance lean mass gains, recovery, and joint comfort (via GH-mediated collagen synthesis), potentially offsetting YK-11's reported joint dryness. This assessment has 95% confidence and is based on documented research data.
How should I time MK-677 and YK-11?
MK-677 has a half-life of ~24 hours and YK-11 has a half-life of ~6-10 hours. No specific timing requirements identified for this combination, but separating administration can help monitor individual effects.
