Foundational Scientific Overview

S4 (Andarine) is a paramount subject within the field of prostate morphology and partial androgenic agonism. As one of the earliest generation of non-steroidal SARMs, it serves researchers examining the competitive antagonism of dihydrotestosterone (DHT) binding in prostatic tissues while maintaining anabolism in skeletal muscle and bone.

At 4-Amino-Labs, we provide this compound in a highly pure format to ensure experimental reproducibility. By maintaining rigorous measurement standards, we provide the consistency required for longitudinal data integrity.

S4 has been investigated in benign prostatic hyperplasia (BPH) models for its activity as an agonist in muscle and a partial antagonist in the prostate. See: Gao, W., et al. (2005). "Chemistry and structural biology of the androgen receptor." Chemical Reviews, 105(9), 3352-3370.
