S-4 ANDARINE

Ultimate Laboratories S-4 (Andarine) , also known as
Andarine, Andarin, S-40503, or GTx-007, is a SARM that
selectively binds to androgen receptors in skeletal muscle tissue.
There is little danger of nonskeletal muscle tissues experiencing
androgen activity. Additionally, research has shown it does not
cause aromatization (conversion of testosterone into estrogen),
liver strain, or severe HPTA (hypothalamic pituitary testicular
axis) suppression. Aside from building lean body mass, andarine
is also used for benign prostatic hypertrophy, muscle wasting,
and osteoporosis.
