Dosage & Research Guidelines

For laboratory research use only. S 23 is a high-potency SARM for research purposes. Proper dosing accuracy is essential. Not for human or veterinary use.

Research Dosing Guidelines

S 23 is a high-potency SARM active at low milligram-level doses. Typical research dosing in animal models ranges from 0.1–1 mg per kg of body weight. Due to its approximately 12-16 hour half-life, once or twice daily administration is common.

  • Oral administration – Standard route for SARM research
  • ✔ One sachet provides 1000 mg total S 23 (100 x 10 mg tablets)
  • ✔ Research cycles typically run 6-8 weeks for anabolic studies
  • ✔ Once or twice daily administration due to half-life

Dosing Guide – Potency Consideration

Using 10 mg tablets – note potency requiring careful dosing:

  • 0.2 tablet = 2 mg S 23
  • 0.3 tablet = 3 mg S 23
  • 0.4 tablet = 4 mg S 23
  • 0.5 tablet = 5 mg S 23
  • 0.6 tablet = 6 mg S 23
  • 0.8 tablet = 8 mg S 23
  • 1 tablet = 10 mg S 23
  • ✔ Administer orally according to research protocol

How Researchers Are Using S 23

S 23 is studied for its high potency and selective anabolic activity. Researchers investigate its tissue-selective androgen receptor modulation and potent anabolic effects in research models.

Popular research stacks include:

  • S 23 + MK 677 – for combined SARM and GH secretagogue research. View MK 677 →
  • S 23 + RAD 140 – for comparative high-potency SARM research. View S 23 →
  • S 23 + GW501516 – for combined anabolic and metabolic research. View GW501516 →

Research Protocol Example (6 Weeks)

  • Weeks 1-6: S 23 – 5-10 mg administered daily via oral route
  • Weeks 1-6: MK 677 – 10-25 mg daily (optional for GH pathway studies)
  • Washout period: 2-3 weeks for S 23 clearance

Important Considerations

  • 🔬 High-potency SARM – active at low milligram-level doses; careful dose selection required
  • 💧 Non-aromatizing – no estrogen conversion; eliminates estrogenic variables
  • ⚠️ Potent androgenic activity – relevant for androgenic research protocols
  • 📦 12-16 hour half-life – once or twice daily administration for sustained studies
  • 📦 Always source Dragon Pharma S 23 10 mg from verified suppliers with batch traceability

Research Note: S 23 is a high-potency selective androgen receptor modulator with significant anabolic activity in research models. Its non-aromatizing profile and oral bioavailability make it a valuable research tool for SARM and anabolic studies. Due to its potency, careful dose selection is essential. Always follow institutional laboratory safety guidelines when handling research compounds.
