What Is GLPG-0492?

SARM

GLPG-0492 is a non-steroidal selective androgen receptor modulator (SARM) designed to bind to the androgen receptor with high affinity while exhibiting tissue-selective anabolic activity. It was originally developed to treat muscle-wasting conditions and muscular dystrophy by stimulating muscle growth and Improving performance with reduced androgenic effects on reproductive organs.

GLPG-0492 Research & Studies

01 Characterization of GLPG0492, a selective androgen receptor modulator, in a mouse model of hindlimb immobilization

This study found that GLPG-0492 effectively prevented muscle mass loss and preserved muscle fiber size in mice during periods of inactivity.

02 GLPG0492, a novel selective androgen receptor modulator, improves muscle performance in the exercised-mdx mouse model of muscular dystrophy

Research demonstrated that GLPG-0492 improved diaphragm and limb muscle function and increased running performance in models of Duchenne muscular dystrophy.

03 Comparison of the three SARMs RAD-140, GLPG0492 and GSK-2881078 in two different in vitro bioassays, and in an in silico androgen receptor binding assay

This comparative analysis confirmed GLPG-0492's strong androgenic potential in prostate cells and provided molecular modeling of its binding to the androgen receptor.

*Based on large scale analysis of publicly available user experiences

Users generally view GLPG-0492 as an effective but 'mild' SARM compared to compounds like RAD-140, with many highlighting its niche status and relative obscurity in the current market.

GLPG-0492 Benefits, Dosage & Side Effects

Effects
  • Muscle Preservation: Reported to be highly effective at maintaining lean mass during caloric deficits or periods of immobilization
  • Lean Gains: Users describe steady, dry muscle gains without significant water retention or bloating
  • Performance Enhancement: Increased endurance and grip strength observed in both animal models and anecdotal user reports
Effectiveness
  • Anabolic Selectivity: Demonstrates a high ratio of muscle-to-prostate activity, reducing the risk of androgenic side effects
  • Recovery Speed: Users report faster recovery times between training sessions and reduced muscle soreness
  • Mild Potency: Often considered less 'explosive' for mass building than LGD-4033 but easier to manage in terms of side effects
Dosage & Administration
  • Common Range: Most anecdotal reports suggest a daily total of 5mg to 15mg taken once per day
  • Starting Dose: Users often recommend starting at 5mg to assess individual tolerance before increasing
  • Cycle Length: Standard cycles typically last 8 to 12 weeks followed by appropriate post-cycle therapy
Side Effects
  • Hormonal Suppression: Like most SARMs, it can cause a temporary reduction in natural testosterone levels, especially at higher doses
  • Lipid Changes: Potential for a slight reduction in HDL (good cholesterol) during the cycle
  • Liver Enzymes: Rare reports of mild elevations in liver enzymes, though generally considered less hepatotoxic than oral steroids
Availability & Sourcing
  • Sourcing Difficulty: Less commonly available than mainstream SARMs like Ostarine, often requiring specialized research chemical suppliers
  • WADA Status: Explicitly listed as a prohibited substance in competitive sports under the S1.2 Anabolic Agents category
  • Research Status: Development appears to have stalled in clinical phases, leaving it primarily in the 'research chemical' market
