Compound Profiles
MK-2866
Selective Androgen Receptor Modulator | Muscle Wasting Research
MK-2866 binds to the androgen receptor (AR) with high affinity and selectivity, functioning as a partial agonist in muscle and bone tissue. Upon binding, the MK-2866-AR complex undergoes a conformational change that promotes nuclear translocation and interaction with androgen response elements (AREs) on DNA, activating transcription of genes involved in protein synthesis, nitrogen retention, and myogenic differentiation.
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..

Frequently Asked Questions
Can I take MK-2866 with MK-677?
Yes, MK-2866 and MK-677 can generally be taken together. MK-677 (Ibutamoren) stimulates growth hormone secretion through ghrelin receptor agonism, while MK-2866 provides direct androgen receptor activation in muscle. The combination supports lean mass accrual through complementary mechanisms without additive HPTA suppression, as MK-677 does not affect the androgen axis. Commonly stacked for body recomposition and lean gain goals.
Is MK-2866 and MK-677 safe together?
Based on documented research, this combination is considered synergistic. However, shared safety flags include: carcinogenic risk, hepatotoxic. Monitor accordingly.
What are the interactions between MK-2866 and MK-677?
MK-677 (Ibutamoren) stimulates growth hormone secretion through ghrelin receptor agonism, while MK-2866 provides direct androgen receptor activation in muscle. The combination supports lean mass accrual through complementary mechanisms without additive HPTA suppression, as MK-677 does not affect the androgen axis. Commonly stacked for body recomposition and lean gain goals. This assessment has 95% confidence and is based on documented research data.
How should I time MK-2866 and MK-677?
MK-2866 has a half-life of ~24 hours and MK-677 has a half-life of ~24 hours. No specific timing requirements identified for this combination, but separating administration can help monitor individual effects.
