Mastorine S23 SARM

S-23, also known as Mastorine, is a synthetic, nonsteroidal Selective Androgen Receptor Modulator (SARM) developed for investigational purposes. It has been studied for its high binding affinity to androgen receptors and its potential role in research related to lean tissue development, receptor selectivity, and anabolic activity. S-23 is recognized for its potency among SARMs and has been examined in various non-clinical models.

Research Focus Areas

• Androgen Receptor Modulation and Selectivity
  S-23 has been found to bind selectively to androgen receptors with a strong affinity, exhibiting tissue-selective activity in investigational contexts. This selectivity is important for differentiating its effects from those of traditional anabolic agents.
• Evaluation of Anabolic Properties
  Research(https://pmc.ncbi.nlm.nih.gov/articles/PMC7108998/) has explored S-23’s capacity to affect lean mass and receptor-related transcriptional activity. It has been studied for its strong anabolic-to-androgenic ratio in controlled laboratory conditions.
• Pharmacokinetics and Dose-Response Relationships
  S-23’s bioavailability and receptor interaction dynamics have been characterized in select studies, providing insight into its structure-activity profile and duration of action.

Potential Observations in Research

• Lipid and Hormonal Marker Changes
  In laboratory conditions, alterations in lipid markers and hormonal pathways have been recorded during exposure to S-23. Further research is encouraged to evaluate these findings in diverse contexts.
• Appetite and Fluid Retention Signals
  Changes in appetite and shifts in fluid regulation markers have been noted as secondary observations in some controlled research settings.

Handling and Dosage Information

Typical research concentrations of S-23 range between 10–30 mg/mL. Volume and method of administration should be selected based on the specific requirements of each research protocol. While some protocols examine sublingual delivery to explore absorption kinetics, this is not required in all cases.

• Store securely in a cool, dry place away from direct light.
• Use calibrated instruments for accurate measurement.
• Follow standard laboratory safety procedures during handling.
