S23 is a selective androgen receptor modulator (SARM) and has been studied and proven to increase muscle mass, reduce fat mass, and has a very high binding affinity to the androgen receptors.

It is non-steroidal and has tissue-selective anabolic effects in muscle and bone, while sparing other androgenic effects that come from anabolic androgenic steroids (AAS).

It also has been shown to decrease prostate size in studies, which is the opposite of a very common negative side effect of anabolic steroids (enlargement of the prostate).

• Notable increases in strength and endurance
• Enhanced levels of fat oxidization
• Can completely off-set catabolism in a calorie deficit
• Body fat melts off much easier
• Greatly enhanced levels of muscle hardness, dryness, and vascularity
• Zero water retention
• S23 falls into the cutter category, and while it could be used in a bulk, due to how strong it is, and how dry of a compound it is, it’s best to save it for cutting phases where the goal is to preserve lean muscle mass, strength, and reach a high level of muscular detail.                                                                                                                                                                                                                                                              DOSAGE AND USE:                                                                                            Total daily dosage of 10mg per day split into three, first taken upon wakening and then every four hours.                                                                                                                                                                                                                                                    LENGTH:                                                                                                             Typical S23  cycle is 4-12 weeks. PCT is HIGHLY recommended.
