OSTA X, otherwise known as Ostarine, is a selective androgen receptor modulator (SARM) designed to help with muscle gain. The SARM primarily focuses on the building of lean muscle. Ostarine boasts no adverse side effects, which makes it a great alternative to other SARMS. OSTA X is commonly mistaken for S1, a SARM that is noted for being possibly the weakest in existence. However, OSTA X is much more potent than S1, especially when it comes to lean muscle. While OSTA X is great for building lean muscle, it has a few other positive effects as well!



OSTA X has undergone 8 scientific trials and 3 efficiency tests. These studies concluded that OSTA X has a real and significant effect on lean muscle growth when compared to a placebo.



When it comes to building muscle, OSTA X provides incredible results with no adverse side effects. It’s not unusual to gain 10 lbs in a short period of time with the help of this SARM. The gains from OSTA X are long term too! The muscle boosting effects of this SARM have been taken advantage of by everyone from bodybuilders to cancer patients. OSTA X provides real gains without the risk of intense side effects, which makes it a boon for a wide variety of people.



Steroids remain the most effective option for building muscle mass, but they come with the risk of several awful side effects, including those that target secondary sex characteristics. OSTA X offers similar muscle gain benefits without side effects of anabolic steroids.



OSTA X is one of the best SARMs that deliver on healthy muscle gain. These gains will all be lean muscle. OSTA X’s anabolic effects work on every part of your muscle tissue, meaning that it helps prevents muscle wasting while also promoting muscle growth. OSTA X also lowers the risk of encountering degenerative issues. Especially when you are recovering from a surgery or other similar conditions. The SARM was also noted to be effective at increasing muscle strength.



OSTA X’s anabolic effects go beyond the muscle tissue, reaching the bone and skeletal muscle tissue as well. It is actively being used to treat conditions that result in decreased bone density, and more medical applications for OSTA X are being looked into often.



OSTA X has no severe or irreversible side effects, provided you take a proper dosage and do not have compromising health conditions. The most commonly reported side effect associated with OSTA X is feeling hot and sweaty after taking it. People also report that it has a bad taste, but that can be fixed by washing it down with something flavorful. Other reported side effects include disrupted sleep and lethargic feelings. These are small issues, and some of the effects are easily countered by other supplements that you may already be taking. Do not overuse the supplement and you will be fine.



Several websites recommend high dosages of OSTA X varying from 25mg to 50mg daily. Those of you who are just beginning to use the supplement should restrict your dosage to 12.5mg every day or even every 36 hours. A lower dosage will still provide the benefits without risk of side effects.
