S-23 20mg by Ultima Pharmaceuticals – Potent SARM for Extreme Muscle Hardness & Strength

S-23 20mg/caps by Ultima Pharmaceuticals features Mastorin (S-23), one of the most powerful SARMs available, known for producing dry, dense muscle, aggressive strength gains, and a hard, vascular look. S-23 is highly anabolic and slightly suppressive, making it ideal for experienced users looking to cut or recomp with minimal fat and water gain.

Used in 6–8 week cutting cycles, S-23 is favored for contest prep, dry bulking, and body sculpting phases where muscle detail and hardness are the priority.

Often stacked with Andarine (S4) or Cardarine (GW501516) for extreme definition or included in PCT-aware cycles.

Men's dosage: 10–30mg/day
Women: Not recommended due to androgenic strength

Ultima-S-23 20mg is ideal for users seeking elite physique refinement, muscle density, and maximum strength without bloating or estrogenic effects.
