What is YK11 ?


YK11 is the latest flavor of the month in the underground gray market bodybuilding supplement world. YK11 is a steroidal molecule that has only been shown to have effects in cellular assays. This means that there are no published results in animals or humans as yet.


Even so it has popped up for sale on the internet as an anabolic SARM or Selective Androgen Receptor Modulator. SARMs are molecules that have the anabolic effects of steroids like testosterone or nandrolone but lack a lot of the negative side effects like hair loss, prostate enlargement and acne.


New age SARMs like LGD-4033 and Ostarine are non-steroidal, meaning that they do not have the typical four ring structure of classical androgens like testosterone.

YK11 Application:


YK11 is an effective and specific synthetic REV-ERB. It also has good in vivo plasma / brain exposure. Nuclear receptors REV-ERB-α and REV-ERB-β play an indispensable role in regulating the expression of core clock proteins, promoting rhythms in activity and metabolism. The circadian rhythm behavior of the mouse hypothalamus and the circadian rhythm pattern of the core clock gene expression were altered by the administration of YK11.

Liver, skeletal muscle and adipose tissue in a series of metabolic genes circadian rhythm expression pattern also changed, resulting in increased energy consumption. Treatment of diet-induced obese mice with YK11 reduces fat levels by reducing fat levels, significantly improving dyslipidemia and hyperglycemia. These results suggest that pharmacological targeting of circadian rhythms of synthetic REV-ERB ligands may be beneficial in the treatment of sleep disorders as well as metabolic diseases.
