YK11 description of what YK11 is
YK11 is a steroidal SARM based on 5-α-dihydrotestosterone. 5-α-dihydrotestosterone (abbreviated DHT) is naturally found in the human body. DHT is basically a stronger form of testosterone. . Except that YK11 has like everyone else SARM the ability to selectively bind to androgen receptors, especially in muscle, an exceptional property of YK11 in contrast to other common SARMs (such as LGD-4033, Ostarine, Andarine or RAD140) is its ability to increase Follistatin expression. Follistatin is a glycoprotein which is a very effective inhibitor myostatin – a protein which inhibits the growth of muscle mass . Thanks to these unique features and capabilities, YK11 can effectively stimulate the development and development of growth of muscle mass .
How YK11 works
YK11 ((1-Methoxyethylidene) bis (oxy)] – 3-oxo-19-norpregna-4,20-diene-21-carboxylic Acid Methyl Ester) stimulates muscle cell growth in both ways – it acts on androgen receptors in the muscles but mainly YK11 increases Follistatin levels . Binding of YK11 to androgen receptors in the body signals skeletal muscle growth. At the same time Follistatin suppresses Myostatin , a protein that normally stops muscle growth. This allows YK11 to significantly increase anabolic activity in the muscles.
Follistatin and myostatin
Follistatin is a protein that is naturally produced in the human body. It is involved in many important bodily functions, including metabolic control, muscle growth, and can even increase fertility. Its opposite Myostatin on the other hand, it is another naturally occurring protein in the body, which in turn is responsible for inhibiting myogenesis – the growth of muscle cells.
YK11, muscle growth and bodybuilding
Unofficial evidence from bodybuilders suggests that YK11 is highly effective at increasing muscle mass . That’s why this is SARM sought after by bodybuilders and strength athletes, who at their own risk try its experimental use for muscle growth.
YK11 benefits, effects, results
- YK11 has a significant and selective anabolic effect on muscles and bones
- YK11 can increase follistatin expression and significantly suppress the action of myostatin
- YK11 supports the growth of muscle mass
- YK11 helps strengthen bones
YK11 possible side effects
Possible side effects of YK11 have not been scientifically studied, so the following side effects are not theoretically excluded:
- Suppressed testosterone levels in the body
- Increased risk of heart attack and stroke
- Liver toxicity (due to the structure derived from DHT)
The bodybuilding community on the Internet and experimental users most often reported these YK11 side effects :
- Mild suppression of testosterone
- Increased aggression
- Joint pain
- Excessive hair loss
- Mild acne
So far, the only available source of information regarding YK11 dosing is the experience of bodybuilders and people who experimented using YK11 at your own risk, published on the Internet. Bodybuilders and users who took sarm YK11 for building muscle mass , most often mentioned as the recommended dosage at which significant results were achieved in muscle growth, the total amount of 10-15 mg YK11 per day, divided into two daily doses.
