Bruising can be caused by alot of things. Remember if anytime your not real steady with the
needle and move it around your essentially tearing muscle fiber. Injecting oil too quickly can cause bruising as well, and anything with test prop in it will cause some people to feel like they are bruised.
The dizziness Im not sure. Did you aspirate the
syringe to make sure you were not in a vein? I know injecting into a vein can cause that to happen. On the other hand Ive hit
veins before but to the best of my knowledge never shot into one and from time to time have had very short spells like you mentioned but perhaps not as severe.
Thats all I can think of right now.
Peace,
