Hey all, I'm in my 5th week of my second cycle, currently running 500mg a week of test e. Saturday I injected into my left glute, upper outer quadrant just like I've always done, when I aspirated I pulled out some blood for the first time. Switched needles, did it again no problems. Earlier today, went for the right glute, pulled out blood again. Switched needles, moved over a little, drew more blood. What gives? This has never happened before, now it's happened three times in a week. If you pull hard enough on the plunger will it always get blood? I aspirate enough to see small bubbles generally, any tips on why I keep getting blood after never having this problem before? Using 22g 1 1/2in needles.
