Stanozolol: Oral vs. Injectable

Everyone knows a drug called stanozolol. True, many know it by the name of the most popular brand – “Winstrol,” rather than by the name of the active ingredient, but that is not so important.

What is important is that stanozolol is usually available either as a suspension for intramuscular injection or in tablet form.

Essentially, it’s the same drug. In reality, however, they turn out to be two completely different drugs – they have almost nothing in common.

Stanozolol is a derivative of dihydrotestosterone (DHT). The stanozolol molecule differs from the DHT molecule only by the presence of a methyl group at position 17 (which protects the substance from complete destruction during the first pass through the liver) and a pyrazole ring attached to ring A (positions 1 and 2).

It is mainly the presence of the pyrazole ring that determines the properties of stanozolol. From its “parent,” stanozolol inherited only the resistance to aromatization – “Winny,” as it is affectionately called, has no androgenic properties.

But it has many other – completely unique – properties, which are worth discussing only after we understand the forms of release of this drug. There are exactly two: aqueous suspension and tablets.
