I have some Test E that i am running with my cycle. I did a shot in each shoulder and then in each butt cheek(2 weeks total) with no issues. then when i went back to my left shoulder about 10 hours after injection had a huge red knot and it was painful for days. took some antibiotics as a precaution and then went to other shoulder 3 days later with same results. big red painful knot. thenm went to butt cheek with same big red painful knot. This did NOT happen the first 4 shots with the exact same vial, just the last 3. anyone had this issue? The Test E is real and really powerful. im not new to aas. i still have a red painful spot about the size of a baseball between my right shoulder and covering my right bicep. I worked out biceps hard the same day i injected my right shoulder and im assuming the combination of whatever the oil did mixed with the hard workout did some inflamation? any help or advice is good. no health insurance so id rather avoid dr. thx amigos
