test isnt any better when mixed with any other steroid. the reaosn you can soemtimes get better gains by mixing another roid with it isnt because the extra roid does anything to the way test works, its because the other roid.... is another roid! more steroids= more effects.
test is probably the only steroid you would want to run by itself, taking into consideration sex drive, estrogen, and everything else. and it is also probably the best steroid, maybe tren as the only exception, for mass and strength gains.
is 1 gram of test enough? its more than enough
