I have never had a problem with this personally, but I was just curious as to what you guys have to say on this matter. What are the effects if the compound which is being injected, gets injected into a vein or artery, thus allowing it to go through into your blood stream? How quick would one notice these effects? Meaning,, if this was to happen...would I have time to react....or would it be so quick, that I would still have the pin in my ass before its too late? I have heard of severe coughing attacks from Test P accidentally getting injected intravenously, but will other compounds do different things? Always aspirate!! Thanks Fellas.
