Dexters Labs Andarine S4 25mg 90 Capsules

Andarine (S-4) – High-Purity Selective Androgen Receptor Modulator – 90 Capsules

Andarine (S-4) is a potent selective androgen receptor modulator (SARM) studied in experimental models focused on body composition, muscle maintenance, and non-steroidal anabolic signalling. Known for its high androgen receptor affinity and dry tissue support, S-4 is commonly used in cutting and conditioning research protocols.

Its oral bioavailability and versatility make it a frequent addition to multi-compound stacks, particularly those exploring muscle definition and hardening-phase outcomes under restricted caloric conditions.

Research Highlights

• S-4 has been shown to bind strongly to androgen receptors in muscle and bone, with limited cross-reactivity in non-target tissues, making it a valuable tool in tissue-selective anabolic signalling research.

• Frequently studied alongside Ostarine, LGD-4033, or Cardarine, S-4 is often selected in cutting-phase experimental protocols aiming to preserve lean mass and improve definition in energy-restricted models.
