Dragon Pharma S4 25 mg – Andarine for Tissue-Selective Androgen Research

✔ Tissue-selective SARM for anabolic research ✔ Lean tissue and bone density studies ✔ USA & International shipping

Dragon Pharma S4 25 mg is a high-purity oral formulation of Andarine, a well-characterized selective androgen receptor modulator (SARM) extensively studied for its anabolic properties in research literature. Each tablet delivers 25 mg of S4, with 100 tablets per sachet. This compound exhibits high selectivity for androgen receptors in muscle and bone tissue with reduced activity in other tissues.

S4 acts as a partial agonist of the androgen receptor, promoting anabolic effects including lean tissue accretion and bone density improvement in research models. Unlike traditional androgens, Andarine is designed to offer tissue-selective activity, making it a valuable research tool for anabolic studies with distinct ocular effects reported in research. For researchers studying selective androgen receptor modulation, tissue-specific anabolic pathways, or SARM pharmacology, Dragon Pharma S4 25 mg delivers a well-characterized research compound. When researchers seek legit Andarine for advanced SARM studies, Dragon Pharma provides batch-traceable, precision-dosed tablets.

Why Athletes & Bodybuilders Are Researching Andarine

Within performance research communities, S4 is studied for its tissue-selective anabolic activity and distinct pharmacological profile. Research focuses on its ability to promote lean tissue and bone density with unique visual side effects in research models.

Dosage & Research Guidelines

For laboratory research use only. S4 is a selective androgen receptor modulator for research purposes. Proper dosing accuracy is essential. Not for human or veterinary use.

Research Dosing Guidelines

Typical S4 research dosing in animal models ranges from 1–5 mg per kg of body weight. Due to its approximately 4-6 hour half-life, divided daily administration is common.

  • Oral administration – Standard route for SARM research
  • ✔ One sachet provides 2500 mg total S4 (100 x 25 mg tablets)
  • ✔ Research cycles typically run 6-8 weeks for anabolic studies
  • ✔ Divided daily administration due to shorter half-life

Dosing Guide

Using 25 mg tablets:

  • 0.2 tablet = 5 mg S4
  • 0.3 tablet = 7.5 mg S4
  • 0.4 tablet = 10 mg S4
  • 0.5 tablet = 12.5 mg S4
  • 0.6 tablet = 15 mg S4
  • 0.8 tablet = 20 mg S4
  • 1 tablet = 25 mg S4
  • ✔ Administer orally according to research protocol

How Researchers Are Using Andarine

S4 is studied for its tissue-selective anabolic activity and distinct pharmacological profile. Researchers investigate its effects on lean tissue, bone density, and unique visual side effects in research models.

Popular research stacks include:

  • S4 + MK 677 – for combined SARM and GH secretagogue research. View MK 677 →
  • S4 + LGD 4033 – for comparative SARM anabolic research. View LGD 4033 →
  • S4 + GW501516 – for combined anabolic and metabolic research. View GW501516 →

Research Protocol Example (8 Weeks)

  • Weeks 1-8: S4 – 12.5-25 mg administered daily in divided doses via oral route
  • Weeks 1-8: MK 677 – 10-25 mg daily (optional for GH pathway studies)
  • Washout period: 1-2 weeks for S4 clearance

Important Considerations

  • 🔬 Tissue-selective SARM – anabolic activity in muscle and bone in research models
  • 💧 Non-aromatizing – no estrogen conversion; eliminates estrogenic variables
  • ⚠️ Shorter half-life (4-6 hours) – divided daily administration for sustained studies
  • 📦 Unique visual side effects reported in research – relevant for ocular studies
  • 📦 Always source Dragon Pharma S4 25 mg from verified suppliers with batch traceability

Research Note: S4 (Andarine) is a tissue-selective SARM with anabolic activity in muscle and bone. Its shorter half-life requires divided daily dosing for sustained research protocols. The compound's distinct visual effects in research models make it unique among SARMs. Always follow institutional laboratory safety guidelines when handling research compounds.
