What is MK-ULTRA (MK-777)?
MK-777, also referred to as Acetamoren, is described as a next-generation analog of MK-677 (Ibutamoren). Like MK-677, it functions as a growth hormone secretagogue, stimulating the natural release of Growth Hormone (GH) and Insulin-like Growth Factor 1 (IGF-1).
What differentiates MK-777 is its positioning as an evolution of MK-677, with claims of improved receptor selectivity, extended half-life, and enhanced oral bioavailability. While awareness of this compound is still limited in the research community, MK-777 is increasingly recognized as a forward-looking research tool for exploring the regulation of GH/IGF-1 pathways.
Chemical Structure of MK-ULTRA (MK-777)
The exact structure of MK-777 has not been widely published, as it is a newly emerging research analog. However, it is understood to be structurally related to MK-677 (Ibutamoren), with modifications intended to improve receptor binding efficiency and pharmacokinetics.
-
Compound Type: Non-peptidic growth hormone secretagogue
-
Mechanism: Mimics ghrelin activity by binding to the ghrelin receptor (GHSR-1a)
-
Proposed Advantage: Longer half-life and improved oral absorption compared to MK-677
What Are the Effects of MK-ULTRA (MK-777)?
Research interest in MK-777 is centered around its potential as a refined version of MK-677. Preliminary supplier claims and positioning highlight the following research areas:
-
Stimulation of GH and IGF-1 Release – like MK-677, MK-777 is believed to increase endogenous growth hormone and IGF-1 levels.
-
Improved Oral Bioavailability – proposed to have enhanced absorption compared to earlier analogs.
-
Extended Duration of Action – a longer half-life may allow for sustained activity with less frequent dosing in research models.
-
Receptor Selectivity – suggested to show stronger binding affinity for ghrelin receptors, potentially reducing off-target interactions.
