Andarine (S4) Review 2019- Benefits & Side Effects

What is Andarine (S4)?


S4 Andarine is a SARM manufactured by GTX, Inc. The compound was initially created by GTX to take care of osteoporosis, muscle wasting, bloated prostate, and several other disorders. These days, it’s has gained immense popularity amongst the bodybuilders who prefer to use Andarine because of its steroid-like advantages.

When it comes to natural, steroid-like benefits, Andarine is usually considered the “weakest” amongst the four most in-demand SARMs on the market. As a matter of fact, the drug was initially produced for medical requirements, and therefore it is not associated with the same harmful side effects as SARMs such as LGD-4033, Ostarine, and the like.

We also refer to S4 Andarine as S4, S-4, or SARM S4 and thus whenever you observe individuals speaking about one of these things it is easy to understand that they are referring to none other than Andarine. Like all products in the SARM series, S4 or andarine is a potent SARM known for its strength gains and fat loss effects. Just like MK-2866 and LGD-4033, S4 was designed to counteract muscle wasting cancer and AIDs patients. Many steroids are considered cutting steroids such as Winstrol or Anavar, and anavar has great strength gains so that S4 can be considered as a bit of a weaker Anavar, but it is usually cheaper.

What is Andarine S4 used for?

For bodybuilding purposes, it is usually combined in conjunction with other SARMs such as LGD-4033, Ostarine and Cardarine, to speed up size gains, strength gains and for fat loss.  It is also very popular for general, cosmetic effects for bodybuilding, as it dries you out slightly, making your muscles look “harder,” it greatly increases vascularity and even has slight joint healing effects.

How does Andarine work?

The behavior of S4 Andarine can be compared with that of the androgen receptors’ orally activated partial agonist. In fact, according to one particular research, it was confirmed that Andarine was responsible for minimizing prostate weight just like finasteride; however, there were neither any decrease in muscular mass nor any anti-androgenic unwanted effect. This is very important since it implies that dihydrotestosterone (DHT) can be prevented by S4 for focusing on receptors without causing any damage to the muscle gains just like a 5a-reductase inhibitor (such as dutasteride or finasteride) might do.

Moreover, Andarine, much like all other SARMS, can affix to the androgen receptors and it does not trigger any androgenic action in the non-skeletal muscular tissues during the process. In reality, there is a general prediction that Andarine can attach around 50% as strong as straight testosterone without causing any androgenic side effect. Consequently, apart from its benefits for the females, it is also perfect for those men who have no intention of coping with androgenic side effects.
