S-23 (Mastorin)

Product Description

S-23, also known as Mastorin, is a potent selective androgen receptor modulator (SARM) investigated for its activity at androgen receptors. It was developed as an experimental compound and has been studied primarily in preclinical research involving androgen signaling, muscle tissue, and reproductive biology.

Unlike traditional anabolic steroids, S-23 was designed to selectively interact with androgen receptors. However, its effects and safety profile in humans have not been adequately established.

Product Information

• Compound: S-23
• Common Name: Mastorin
• Category: Selective Androgen Receptor Modulator (SARM)
• Research Status: Investigational
• Intended Classification: Research use only

Research Overview

Preclinical research has investigated S-23 for its strong androgen-receptor activity and potential effects on muscle and reproductive pathways. Studies have also examined its potential influence on male reproductive function, making it a compound of interest in contraceptive research.

Potential Risks & Considerations

S-23 has not been established as safe for human use. Potential concerns associated with androgenic activity may include hormonal suppression, alterations in reproductive function, changes in cholesterol levels, liver effects, and cardiovascular risks. Long-term effects remain insufficiently characterized.
