2a,17a-dimethyl-17b-Hydroxy-5a-androstan-3-one (Superdrol)

Yet another nomenclature for Superdrol.

2a,17a-dimethyl-17b-hydroxy-5a-androstan-3-one and 2a,17a-di-methyl-etiocholan-3-one,17b-ol are the same exact compounds written differently. They are both methylated at the 2a and 17a positions, both have a hydroxyl (alcohol, -OH) group at the 17b potion, and a ketone at position three. Just one attempts to use the term etiocholan, which isn't used too often.

2a,17a-dimethyl-17b-hydroxy-5a-androstan-3-one is a derivative of Drostanolon (also called Dromostanolone), which is also known as the commercial AAS Masteron. Drostanolon has a chemical structure of 2a-methyl-17b-hydroxy-5a-androstan-3-one. Drostanolon is the 2-methylated form of DHT, so it has typically been used for reducing body-fat and water retention, while increasing muscle hardness and density, as it cannot form estrogen.

2a,17a-dimethyl-17b-hydroxy-5a-androstan-3-one is a derivative of Drostanolon, except it is a di-methyl instead of a methyl. It has one methyl in the 17th position, just like M-1-t and M-Dien, but it also has a 2nd methyl in the 2nd position.

This is how the derivative is different from standard Drostanolon, in that it has another methyl in the 17th position. Standard Drostanolon has one in the 2nd position, and not the 17th like M-1-t.

Also, it is a saturated modified form of anadrol, so you get the best of both worlds without the progesterone, estrogen, bloat, hypertension problems with anadrol.
Zero estrogen conversion, because it's 5-reduced and A-ring alkylated. Also, the parent compound (masteron) is used exclusively as an anti-neoplastic for metastatic breast cancer, so it's a strong anti-estrogen.

The chemical has been named methasteron and the product Supderdrol.
