If its a huge concern then the breakdown of 500mg is this;

Prop=425
Enth=340

Difference of 100mg of Test E. So 500mg of Test E is comparable to 400mg of prop.
Now! Do you now what the difference in the effect of that 100 mg (85 of actual test) would be? NOTHING NOTICABLE!

I agree...consider your timing and schedule. By the way...when you say dug test, what are you refering to. Very few employment tests are for AAS!
