Buy YK-11 Online

YK-11 Sarm is a new synthetic steroid based on 5-α-dihydrotestosterone (DHT), a hormone naturally found in the human body. DHT is a stronger form of testosterone that targets androgen receptors in the prostate, sex organs, hair, and liver. Buy YK-11 Online

YK-11 is gaining interest from bodybuilders due to its ability to quickly build muscle with minimal side effects, much like various SARMs. The structure of YK-11 is unique. The YK molecule shares more in common with steroids than SARMs, although it’s often mistakenly placed in the same bucket as all other non-steroidal SARM.

One cellular study suggests that YK-11 increases muscle mass. Researchers found that it increases the muscle-building protein follistatin (a myostatin inhibitor).

YK-11 may also enhance bone health. In a study on bone cells, YK-11 increased the levels of bone-building proteins.

Some bodybuilders who have experimented with YK-11 report great muscle gains and fat loss with minimal side effects. However, there are currently no animal or human studies of YK-11 and its safety is unclear. Buy YK-11 Online

YK-11, along with all steroids and SARMs, is banned in professional sports by the World Anti-Doping Agency.

Is YK-11 a SARM?

Bodybuilders and researchers sometimes refer to YK-11 as a SARM (selective androgen receptor modulator). This may be misleading as other drugs that are traditionally called SARMs differ from YK-11.

YK-11 is a steroid made by directly altering the chemical structure of DHT. In contrast, all other SARMs have a nonsteroidal structure. YK-11 and SARMs work differently in the body and may have different side effects.

Cell studies do show that YK-11 has a selective effect on androgen receptors. This means the SARM label does technically describe YK-11.

Because this class of drugs is so new, no established naming convention exists. Based on its activity and chemical structure, it may be more appropriate to call YK-11 a synthetic steroid rather than a SARM.

How Does YK-11 work?

The chemical structure of YK-11 is similar to DHT and it binds to androgen receptors in a similar way. DHT is a naturally occurring hormone in the body, crucial for hair growth, prostate health, proper development in puberty.

Some bodybuilding resources state that YK-11 is one of the strongest SARMs on the market. However, research revealed that YK-11 only partially activates androgen receptors and prevents full activation. Such limited activation increases the activity of catabolic androgenic genes.

Importantly, YK-11 is also a myostatin inhibitor. A recent cell study uncovered the basis of YK’s unique muscle-building mechanism: increasing follistatin levels. Follistatin is a naturally occurring protein in that suppresses myostatin, which otherwise prevents muscles from getting too large. In comparison, no other SARMs show myostatin inhibition.

YK-11 may also increase bone growth by affecting a DHT like pathway, according to other cellular studies. YK-11 activates protein kinase B (PKB), which sends signals to increase the activity of bone-building cells.
