What is the androgen receptor ( AR ) ?  

AR ( androgen receptor ) is a member of the nuclear receptor superfamily of steroid hormones , which includes receptors for estrogen , progesterone , glucocorticoids , and halocorticoids .  

Binding of the endogenous androgen , testosterone , and the important active metabolite , dihydrotestosterone ( DHT ) , to the AR triggers a series of significantly different bioactivities that vary with the sex , age , and hormonal status of the user .  

AR activity is essential for normal human sexual development and function , but in addition to this signature role , AR activation has important effects on various targets such as bone , liver , muscle , and central nervous system .  

The therapeutic potential of androgen signaling is widely recognized in the chemical community , and for quite some time chemists have sought compounds that selectively stimulate bone and muscle growth while minimizing effects on sexual tissues such as the prostate .  

This kind of compound is named as SARM . It selectively acts on bone and muscle to promote muscle growth and bone health , which is the basic role of SARM . RAD 140 is a type of SARM . 

SARMs RAD 140 Review benefit  

SARMs RAD 140 Review -Benefit of Gain strength and muscle  

SARMs RAD 140 has high synthetic metabolites and provides great force gain , it is an important substance for breaking stagnation and records .  SARMs RAD 140 increases the production of red blood cells and therefore increases the blood supply to muscle tissue, and a significant increase in strength is seen within 3 to 4 weeks of the cycle .  

One Bodybuilder using SARMs RAD 140 noticed that his endurance level increased from week 4 onwards .  "It wasn't crazy at first , but I noticed that my normal weight seemed easier to control , and I felt like I had more power to do it a few more times . "  

"By the seventh and eighth weeks I felt strong enough to start putting on 5-10 kilos .  I also noticed that my collection seemed to pass more easily . "  

There are also Bodybuilder is in the use of SARMs RAD 140 2-3 days , can feel SARMs RAD 140 began to work , which is affected by the individual differences of users .  

Bodybuilder using SARMs RAD 140 cycles for about 6-8 weeks can increase 4-6 kg of pure muscle mass , muscle clarity and tear effect both good .  

Working Hard can lead to tiny tears in the muscle tissue .  To repair these tears , cells accelerate division , and SARMs RAD 140 promotes protein synthesis , allowing more cells and tissues to fill the gap .  Thus , more muscle is added .
