Also known as Winstrol, Winny

An oral DHT derivative, historically used for hereditary angioedema.

Non-medical dosing is around ten times the licensed dose, and the effect on lipids is the most severe of any compound in this category.

How it works

A DHT derivative carrying a pyrazole ring, 17-alpha-alkylated for oral use. Does not aromatise and binds SHBG strongly, which raises the free fraction of anything else being run alongside it.

Shape of a single dose, modelled as one compartment with first-order absorption. The peak is normalised to 100% because bioavailability and volume of distribution are not published for most of these compounds.

About 9 hours for the oral form. The injectable aqueous suspension behaves quite differently and is not covered by this figure.
