S4 25 mg

Dragon Pharma S4 – Andarine for Cutting, Muscle Preservation & Strength

Dragon Pharma S4 contains 25 mg of Andarine per tablet, with 100 tablets per bottle. Known for its unique ability to promote fat loss while preserving lean mass, S4 is a selective androgen receptor modulator (SARM) that enhances vascularity, strength, and definition. It's especially popular during cutting or recomp phases where hardness and muscle retention are key.

What Is S4 (Andarine)?

S4 is a SARM developed by GTX Inc. for treating osteoporosis and muscle wasting. It selectively targets androgen receptors in muscle and bone tissue without converting to DHT or estrogen, making it a clean alternative to anabolic steroids. S4 can help improve performance, body composition, and strength with fewer side effects [NIH Source].

How to Use Dragon Pharma S4

Dragon Pharma S4 is typically dosed at 50 mg per day, split into two 25 mg doses (morning and evening). Due to its relatively short half-life (4–6 hours), split dosing is ideal. Cycles last 6–8 weeks. Note: some users report mild visual side effects (e.g. yellow tint, night vision adaptation issues) which reverse post-cycle.

S4 stacks well with non-suppressive SARMs like GW501516 or with MK 2866 for a lean recomp approach.

Effective Cutting Stacks Featuring S4

• MK 677 – supports recovery and fullness during a deficit
• Clenbuterol 40 mcg – for fat-burning synergy
• S 23 – for hardening and extreme physique refinement

S4 Benefits

• Increases strength and muscle density
• Enhances vascularity and definition
• Promotes fat loss without muscle loss
• Non-liver toxic and non-aromatizing

Post Cycle Therapy (PCT)

S4 is mildly suppressive at doses above 50 mg/day or cycles longer than 6 weeks. A light PCT is advised for recovery. Use Clomid or Enclomiphene for 3–4 weeks post-cycle to restore hormonal balance.

Side Effects

The most common side effect is temporary vision disturbance (yellow tint or difficulty adjusting to low light). This subsides after discontinuation. S4 does not affect estrogen or liver enzymes and is generally well-tolerated when used responsibly.
