Dose of aspirin in a ECA stack??

I am doing a ECA stack, something I am not TOO familiar with but have been on it a week and have found the results are better from this stack than any steroid stack I have done in the past. Huge pumps in the gym, muscle definition is much geater than before, lots of energy, in a better mood throughout the day. I have not taken any aspirin yet but I am wanting to incorperate it in. Right now I am taking 16mg(E), 200mg(C) at 9:30am and then again at 2:30pm. I know this is a fairly low dose but keep in mind my BF% doesnt ever get over 10% so coming down that little bit more doesnt take much. Anyways, what is a noraml dose of aspirin in an ECA stack and would it be best to take it with the EC or at different times throughout the day??

children's aspirin 81mg is what i use
