Brand: Ultima Pharmaceuticals

Substance: Mastorin

Action of the Drug

S-23 (Mastorin) is a selective androgen receptor modulator (SARM) designed to promote lean muscle growth, increase strength, and enhance overall physical performance while minimizing androgenic effects.

Use in Sports

Ideal for bodybuilders and athletes looking for lean mass gains, improved strength, and better athletic performance without the side effects associated with traditional anabolic steroids.

Period of Drug Withdrawal

S-23 has a half-life of approximately 12 hours, with complete elimination typically within 7–10 days after the last dose.

Rate of Suppression of Natural Testosterone Production

S-23 can significantly suppress natural testosterone production; post-cycle therapy (PCT) is recommended to restore hormonal balance.

What Should Be Used During and After Use

During use:

• Support supplements for liver and overall health
• Maintain a high-protein diet for optimal muscle growth

After use:

• Post Cycle Therapy (PCT) to restore testosterone levels
• Continued nutrition and training for retention of gains

Combinations with Other Anabolic and Androgenic Drugs

S-23 can be stacked with other SARMs or mild anabolic compounds for enhanced muscle density and cutting results, depending on the user's goals.

Possible Side Effects and How to Avoid Them

• Testosterone suppression – managed with PCT
• Potential mild hair loss or acne – controlled by dosing
• Altered lipid profile – monitor diet and cardiovascular health
