Andarine acts as an oral active partial agonist of the androgen receptors. To be sure, one study showed that prostate weight reduced as finasteride does, but without the anti-androgenic side effects or reduction in muscle mass.
This is an important fact, since then we see that S4 blocks dihydrotestosterone (DHT) by binding to target receptors without damaging the muscle it gains as a 5-reductase inhibitor (such as finasteride or dutasteride) would have done. As a result, andarine could help maintain the head of the hair while using anabolic steroids, and help avoid the side effects of drug like finasteride.
Moreover, just like all bosspeptides SARMS, andarine will attach the androgen receptors without causing androgenic activity in skeletal-non-skeletal tissues.
In fact, it is estimated that about half will attribute powerfully as straight testosterone, but will not cause the androgenic side effects found with the latter. Therefore, this is not only great for females, but it is also great for those males who do not want to deal with androgenic side effects.
As mentioned above, athletes make use of the medical benefits of andarine, and translate them into athletic benefits. For example, andarine is extremely popular in crossfit, where the athlete can benefit from gains in muscle mass and improved endurance, while not having to carry around extra water because it does not cause swelling.
Furthermore, it is also capable of increasing endurance, fat reduction, and helps with bone / joint health.
In my personal experience, I was able to gain strength quite quickly on S4 without adding any body fat, water weight, or decreasing my stamina.
This makes it a great compound for powerlifters trying to make their weight class. What is more, it is also a great addition to a cutting stack because it works well with DHT derivative compounds. When stacked, it will counteract these most common negative side effects and maybe even prevent hair loss.
Despite the fact that boss peptides andarine S4 can only be correctly used, for the best synergy I recommend you stack it as part of a double or triple SARMS stack. An example of this would be Cardarine (GW501516), LGD-4033 (Anabolicum), and S4; or GW, Ostabolic (Ostarine), and S4. Another good combo is Nutrobal (mk677) with Andarine and Ostabolic.
Another way to run S4 would be as an addition to an existing anabolic steroid stack because it will give more benefits to your cycle without adding to the side effects. S4 fits particularly well for those who want a boost in strength, endurance, lost fat, or joint health.
