That it would. They are both alkylated, so the liquid version wouldn't get broken down by your liver. Although, by injecting it you avoid first pass through the liver so it is less damaging. To each his own I guess.
On another note, Chemone's anastrazole is quite tasty =)
EDIT: Although, the plasma concentration curves show a difference in the concentration of any drug between injected IM and taken orally. The oral route raises the plasma concentration faster.
