So today I injected 1ml of Test C and 1ml of Tren A into my quad with a 23G x 1 needle same thing I always do. I pinched the skin stuck the needle all the way in retracted it no blood so I started to inject got 1ML in waited a couple of seconds then did the rest and still kept the needle in for a few more seconds. When I took out the needle a LOT of blood came out. My alcohol swab was red after and blood dripped on the floor, there was a lot of blood but it didn't last very long until it stopped. What do you guys think could have happened? I did the exact same thing 2 days ago with my left quad and no blood came out what so ever.
