My mouse had a heavy push on chest day.Post workout i decide to inject his chest with PEG MGF.I was sloppy and didnt asperate.Definitely caught a vein or artery.Heart rate immediately when through the roof.He turned red and blood pressure crazy high.Fortunate for me i had morphine to inject alond with a beta blocker and aspirin. If not ,the mouses girl friend Minny would have called 911.She wanted to call 911 anyway.Even 20 minutes after morphine and beta blocker heart rate was still 120 and BP 180/100+...It was a VERY SCARY situation.Please asperate when using this product.I never previously had any sides.
