Can I mix Susp. w/ Test 400 in the same shot?

I have some left over Test 400 (about 5cc) and Test Suspension (about 15 cc).
I used to get bad reactions from the 400 shots and was wondering if I can mix them in the same shot? Maybe a small amount of each as in half a cc of each or one cc of each?
Anyone have any ideas on this one?
Thanx bros and PEACE TO ALL MY AMERICAN BROTHERS AND SISTERS WHO ARE RAW TO ENDURE TIL IT'S TIME TO KICK SOME ASS!!!!!!!!!
:mad:

......also

If it is possible to mix the two should I extract one before the other? Shoul I shake them together? Just wondering.
Thanx again.
Peace!

but suspenion usually in painful shot, plus the t400 is a nasty shot so i hear, better off mixing with eq or deca
