Just started third week of Test E, 500mg/week, and Eq, 500mg/week. Been injecting two times a week, alternating right glute, left glute, right glute, left glute. Well, yesterday I was scheduled to hit the right glute, but a week after the last injection the right glute is still sore. I opted to hit the left glute again with no problems. There is no redness, swelling, or heat on the right glute, just sore in the muscle. I did a search and found that it's possible for the oil to form a ball in the muscle??

Am I correct to assume this is built up oil from the first two injections in the right glute?
