thats what happens when you don't aspirate and you inject in a vein by accident

first off, you are too young for aas, secondly you may not have hit a vein, i recently started my first cycle, ive always not been a big fan of needles, before my first shot i got myself soooooo worked up about that afterwards i got sweaty for a few minutes too, was just nerves as i did aspirate and all that, im glad i do, tuesday morning I hit a vein.
