Just because I'm a Testaholic I'm going to throw in my .02cents.....Virormone Test Prop from Ferring Pharmaceuticals is my choice.
And just a note to these test is test dudes! You are right Test is Test....but....some hurt like holy hell and leave welts on your arm, ass, and thighs that can last days and affect your training in the gym. So in a sense, Test is not Test. Sure Ttokkyo Test Prop is exactly the same thing as Virormone, but damn, Virormone gives me better gains (possibly a placebo cuz I love it so much) and doesn't hurt like a son of a bitch.
