What is LGD-4033 (Ligandrol)?
LGD-4033 (Ligandrol, VK5211) is a highly potent nonsteroidal SARM with near-full AR agonist efficacy. Among the strongest anabolic SARMs in clinical research — demonstrated lean mass accretion in Phase I studies. Research tool for AR full agonism, muscle hypertrophy models, and high-potency SARM pharmacology. Research use only.
Research Applications
High-Potency AR Full Agonism
Near-full efficacy AR activation — Emax close to testosterone, potency ranking
Lean Mass Research
Muscle protein synthesis, satellite cell activation, myofibre hypertrophy
SARM Reference Compound
High-potency full agonist benchmark — comparison anchor for weaker SARMs
HPG Axis Suppression
Dose-dependent LH/FSH suppression, testosterone suppression, recovery kinetics
Clinical-Grade SARM Research
Phase I-validated compound — translational muscle wasting and sarcopenia research
