For a long time, S-4 or Andarine was believed to be the answer that researchers had long been seeking.


The perfect selective androgen receptor modulator that could prevent muscle wasting and reduce the risk of benign prostatic hyperplasia.


Phase-I Human clinical trials happened. The results were said to be extremely positive.


Everything was hunky dory.

And then suddenly, the trials were dropped in favor of a more Ďeffectiveí SARM, called Ostarine.


For any chemical to have trumped something as potent as S-4, itíd have to be pretty dope.


Thatís precisely what Ostarine is. It is one of the most effective SARMS that you can use often called by bodybuilders as the perfect SARM.


Something thatís as close to exogenous testosterone as it can get. In fact, most users compare the results with what you can achieve with EQ or Anavar clubbed with test.


It also has the distinction of being the only SARM to have been researched multiple times on humans.


But what does it bring to the table for an athlete, a bodybuilder or an amateur trying to break their threshold?


Letís find out.

What is Ostarine?
Ostarine, MK-2866, GTx-024 or Enobosarm is a SARM that is developed and researched by GTx laboratories as a potential therapeutic aid to prevent muscle wasting caused due to cancer.


As we briefly mentioned, it has been extensively studied by multiple research agencies.


In fact, GTx still has studies underway on Ostarine after more than a decade and a half.

That in itself speaks volumes about its perceived potential therapeutic uses. One day, it might replace a lot of side-effect inducing medicines that we use.


But if not for the bodybuilding community, Ostarine would be an unknown research chemical at best.


Bodybuilders started to tap into it way back in the early 2000s once the research data became public and since then, it has remained one of the most popular SARMS in the world.


Professional sporting organizations along with WADA have banned Ostarine way back in 2008 labelling it an ĎS1 Anabolic Agentí.


How flattering!
