What it is: A stronger SARM often described as more “steroid-like” in feel.
Research snapshot: Mostly preclinical; limited human outcome data; this was originally researched as a male contraceptive, and worked very well.
What users report: Strength/hardness; sometimes appetite shifts; sometimes harsh feel. This one can cause skin issues due to testosterone shutdown and related estrogenic side effects from an improper balance. Some users report that this is by far the strongest SARM, likening it to a dry Anadrol. Some users report gains in the 20lb range, although, diet and training play a critical role in this.
Common downsides: Suppression is usually reported; lipids often worsen; tolerability can be rough.
Watch-outs: If biomarkers matter to you, S23 is typically treated as a “more serious” choice.
