Hi, noob to the forum here. Been on test since about Feb or Mar through my doc. 1.5ml of Testosterone Cyp (2000mg/10ml) every 10 days. I use the z technique and meticulous about sterile procedures and alcohol wipes. Draw with an 18ga, administer with a 22ga x 1 in quads, relaxed not flexed (I could honestly care less about needles or sticking so that's not an issue for me), rotating quads each dose. Other than normal injection site pain, and a little blood every once in awhile, all has been good. Dosed myself on 11/7 and it bled a little more than normal. 11/8 there was a tightening and pain greater than normal. 11/9 soreness increased, slight bruising around injection site, a light redness, still tight and tender to the touch, and a little warm. This has persisted till now. Called my doc, he can't see me for a few days due to surgery schedule. Did I just miss the muscle? Bad placement? Not seeing where I can post the pic of it to show. Any help is appreciated.
