so was doing my pin of test e 250 mg/ml. when i pulled back the syringe blood came out ( this is the first time ive hit a blood vessel and blood actually went into the syringe). i took the needle out and found a different spot and only air came out so i hit the plunger. about 15 seconds pass and i start to feel light headed and i start to taste the oil in my mouth ( this is the first time ive ever tasted the oil and i read when you hit a blood vessel that is one of the first symptoms). did just a little bit from the tip of the needle go in is that why i only experienced the taste side effect and not the coughing fits?
