I have been bruising very easily lately.. I can't figure out what it is.

I am currently on 1ml of sus 325 on Monday and Thursday and that may be the cause??

Also I am taking some BCAA's that have what seems to be lots of magnesium because you can see it settle at the bottom, I drink this shit all day with my gallon of water. So about 6 scoops per day.

Anything else that would cause bruising like this?

This pic is a bruise from a squat machine with very thick pads on the shoulders, no reason I should have bruised this easily and this is the second time I have noticed this.
