I just injected my boy, with some prop/test, i know for sure i went through a vein but aspirated and it was fine, when i pulled out there was ALOT of blood coming from the site he held an alchhol swab on there for a couple mins and the bleeding finally slowed but now there is a tiny lump there and it is very sore to rub..BTW i used a 1" 25g pin and went all the way in so i would think that it is no0t the oil at the surface?? What do you guys think?
