Foundational Scientific Overview

S23 is an immensely potent subject within the field of reproductive endocrinology and advanced muscle hypertrophy models. Synthesized as a fully penetrant, non-steroidal SARM, it has become a staple for researchers examining extreme binding affinities to the androgen receptor and its potential applications in temporary male hormonal contraceptive modeling.

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

The interaction between high-affinity SARM binding, total suppression of spermatogenesis, and concurrent preservation of lean mass is a cornerstone of male contraceptive research. See: Jones, A., et al. (2009). "Preclinical characterization of a (S)-N-(4-cyano-3-trifluoromethyl-phenyl)-3-(3-fluoro, 4-chlorophenoxy)-2-hydroxy-2-methyl-propanamide: a selective androgen receptor modulator for hormonal male contraception."

Analytical Composition and Purity

Purity≥99%via HPLC

FormulaC18H13ClF4N2O3

Physical StateClear solution, 25mg/mL in PEG-400 / Ethanol (raw material: fine white crystalline solid)

Investigational Pathways

Spermatogenesis Inhibition

Evaluating the compound’s suppression of LH and FSH, leading to a reversible absence of sperm production in pre-clinical testicular models.

Extreme AR Agonism

Observing the profound upregulation of muscle protein synthesis and bone mineral density that vastly outperforms earlier SARM generations.

Glucocorticoid Antagonism

Investigating the agent’s capacity to outcompete cortisol binding, reducing catabolic tissue breakdown under stress.

Laboratory Handling and Stability

Thermal Regulation

Store in a strictly controlled, desiccated environment at room temperature.

Photostability

Protect from direct UV exposure; storage in an opaque container is advised.

Contamination Control

Utilize sterilized instruments and work within a laminar flow hood where possible.
