why do i bleed more with shots????

[big phenom]

I started doing site injections into my thighs and love it painless and can be and easy.....But when I go back to shooting 2cc's in my ass.....I find it more painfull and I am starting to get more bruises...I never had a problem before...even when I shoot 1cc ....What the fuck is wrong.? Overall this is my forth cycle so I know how to do it right.....someone help need some advice.

I find that site injecting into areas that I trained that day makes them bleed more (even hours after training). Not sure if that's your case here but just what I have been noticing moreso recently...
