LGD-4033
LGD-4033 Product Description — Research Use Only
LGD-4033, also known as Ligandrol, is a research compound studied as a selective androgen receptor modulator, commonly known as a SARM. It is not a peptide, but it is often grouped within peptide and research-compound catalogs because of its use in androgen-receptor, anabolic-pathway, lean-mass, and body-composition research.
Research on LGD-4033 has most commonly focused on androgen receptor activity, lean-mass markers, muscle-support pathways, strength-related research, bone-support signaling, hormone-response markers, and tissue-selective anabolic activity. Published research describes LGD-4033 as a nonsteroidal oral SARM studied for safety, pharmacokinetics, lean body mass, muscle strength, stair-climbing power, and sex-hormone response markers.
LGD-4033 is commonly studied for:
Androgen receptor activity — how the compound interacts with androgen receptor pathways
Lean-mass research — markers related to lean tissue and body-composition changes
Muscle-support pathways — signals connected to muscle growth, repair, and protein balance
Strength-related research — markers connected to output, force, and physical performance
Bone-support pathways — research involving bone maintenance, density, and structure
Tissue selectivity — how activity may differ between muscle, bone, and other tissues
Hormone-response markers — how androgen-related pathways influence biological signaling
LGD-4033 is commonly studied because SARMs are designed to activate androgen receptor pathways in a more tissue-selective way than traditional steroidal androgens. In a controlled study of healthy young men, LGD-4033 produced dose-related increases in lean body mass over 21 days, while broader SARM research describes the class as being investigated for muscle and bone-related anabolic activity.
