AS All at once or split injections up

If one was going to be injecting...say 500mg Test and 400 MG of EQ per week
would it be better to take one shot of each ( half test + half eq) on on day and the second half on the next day ?? Or would it be okay to just take all the test (500mg) one day and then all the EQ.

Is there an advantage doing it either way ??

split it up into 2 injections per week, one on say sunday and the other on wednesday, keeps the blood levels more stable.
