YK-11, a novel Selective Androgen Receptor Modulator (SARM), has gained widespread attention in recent years for its potential therapeutic applications. This paper aims to describe YK-11, focusing on its biochemical profile, mechanism of action, and potential applications.


Selective Androgen Receptor Modulators (SARMs) are a class of therapeutic compounds with similar properties to anabolic steroids but with reduced androgenic properties. Among these, YK-11 has garnered interest due to its unique biochemical profile and potential for various therapeutic uses.

Biochemical Profile:

YK-11, chemically known as (17-alpha,20E) 17,20-[(1-methoxyethylidene)bis(oxy)] 3-oxo-19-norpregna-4,20-diene 21-carboxylic acid methyl ester, is a synthetic steroidal SARM. YK-11 is structurally divergent from the traditional non-steroidal SARMs, sharing a closer resemblance to dihydrotestosterone (DHT), a naturally occurring androgen.

Mechanism of Action:

YK-11 operates by selectively binding to androgen receptors, particularly in muscle and bone cells. Its partial agonistic activity at the receptor level distinguishes it from typical SARMs, allowing for a unique biological effect. It is proposed that YK-11 induces its effects via the follistatin pathway, elevating the levels of this protein to promote muscle cell growth and differentiation, though the exact mechanism remains under investigation.

Potential Therapeutic Applications:

Given its biochemical profile and mechanism of action, YK-11 has been proposed for several potential therapeutic applications. It is important to note that most of these applications remain hypothetical, as rigorous clinical trials have not been completed as of this writing, and hence the product is currently not intended for therapeutic use in humans.

Muscle Dystrophy: Pre-clinical studies suggest that YK-11 may have potential in the treatment of conditions characterized by muscle wasting, such as muscular dystrophy. By selectively targeting androgen receptors in skeletal muscle, YK-11 could hypothetically aid in muscle preservation and growth.

Osteoporosis: The bone anabolic effects of YK-11, attributed to its selective action on androgen receptors in bone tissue, may indicate a potential use in osteoporosis. This compound could theoretically support increased bone density and strength, alleviating the common osteoporotic symptoms.

Aging: As an individual ages, they experience a natural decline in muscle mass and bone density. YK-11, with its selective androgen receptor modulating activity, could potentially slow down or reverse these aging-associated declines, though much more research is needed to substantiate this hypothesis.

Challenges and Future Research Directions:

Despite the potential of YK-11, several challenges remain. The compound’s safety profile has not been fully established, and it is currently not approved for medical use in humans. Moreover, its exact mechanism of action and the long-term effects of its use remain uncertain. Comprehensive, long-term studies are needed to validate the therapeutic potential of YK-11 and to evaluate its potential adverse effects.


In conclusion, YK-11 is a novel SARM with a unique biochemical profile and a potentially wide range of therapeutic applications. However, it is important to underscore that the product is currently intended for research purposes only and is not recommended for therapeutic use in humans until further research confirms its efficacy and establishes its safety profile. Future research should focus on elucidating the exact mechanisms of YK-11, establishing its safety profile, and validating its potential therapeutic uses in rigorous clinical trials.

Note: This information is intended to provide an overview of YK-11 based on available research and should not be construed as medical advice or a recommendation for use. Use of YK-11 should be in compliance with local laws and regulations and should be undertaken only under the guidance of a qualified health professional or researcher.
