Ligandrol LGD-4033

One of the more thoroughly studied experimental muscle-building compounds (also called LGD-4033), tested in a real human trial in healthy men. That trial showed it does build muscle, but it also lowered testosterone and 'good' cholesterol, confirming both the benefits and the downsides typical of this drug class.

Also known as LGD-4033, Anabolicum, 1EJT54415A, Vk5211, LIGANDROL [NFLIS-DRUG], LIGANDROL (NFLIS-DRUG), RefChem:902038, Ligandrol (LGD-4033), C14H12F6N2O

Also known as LGD-4033; reached Phase II human trials showing lean-mass gains, but was never approved. Not FDA-approved; sold only as a research chemical, and has been linked to suppressed natural testosterone production even at these 'typical' doses.
