ok guys whats up? my boy is on the juice. today he accidentally forgot to check if he hit a vein before he injected, when he pulled the needle out some blood came out. he shot in his upper left butt cheek. my question is what could happen if he actually shot into the vein? how longwould it take before somethig would happen. he took it like 10-15 mn ago and so far he's ok. usually he could feel the juice enter his muscle, this time he felt no liquid. please help me. i'm worried that he messed up. what could happen and how fast could it take place?
