Andarine’s full technical name isn’t S-4. The full name of this compound is actually S-40503 but for the purpose of convenience, it’s been called S-4 for short. This substance has been discovered by the Japanese pharmaceutical company Kaken Pharmaceuticals as a treatment for a bone condition known as osteoporosis. This Selective Androgen Receptor Modulator has different versions and the stronger one is called Andarine.

Current animal tests are still ongoing and the substance is intended for research and testing alone and not yet recommended for human recreational use.

How Andarine Works

Andarine (S-4 or S4) effectively binds itself with the androgen receptors that are found in the bones and muscles. It’s not as effective in muscle building lean muscles like Trenbolone but works effectively in burning fat. It is able to do so because of its high androgenic effect and less of the anabolic properties which is one of the best among the SARMs in the market at present.

The burning of fat starts when hormones with androgenic properties (or SARM in this case) binds with the receptors for androgen present in the fat tissues (adipose tissues). Andarine strengthens and preserves the bones and even increases its mass. The effects are selective which means that it causes no harm in other internal organs like the prostate and liver. At low doses, Andarine produces weak muscle building effects while at higher doses, it can aid in the development of lean muscles without the androgenic side effects that Winstrol and Anavar produces. These tests were performed in animals and more research is still needed

Possible Benefits of Andarine

SARMs like Andarine (S4) are not to be considered steroids because they produce less anabolic and androgenic effects. Andarine’s benefits include the following:

• Aids in the development of lean muscle mass
• Helps increase fat-burning activity
• Brings vigor and endurance to a higher level even in low-calorie diet
• Gives great physique with hard muscles
• Can be taken together with other SARMS

NOTE: Tests were done only in animals and no conclusive evidence exist that this SARM is safe for human use.

Possible Side Effects

Although not as suppressive as LGD-4033, Andarine still possesses this effect especially at higher doses more than Ostarine. It is theorized that a post cycle therapy is done after a full cycle of use. Using HCGenerate to help cure the little suppression caused has been reported to produce good results while mini-pct is also found to be great for recovery.

Andarine also binds with the receptors found in the eye which causes a faint yellowish tint that can sometimes make it hard to see through mild darkness but it’s not seen in all animals subjected to trial. This side effect also goes away after discontinuing the use of the substance. No estrogen inhibitor is required in the entire cycle as it does not turn into estrogen in the long run.
