Gentlemen, Im currently in the 4th week of my 2nd cycle Ive ever ran. Shooting twice a week in my glutes. This is the second time on this cycle that ive had this problem. The day after I enject, the whole side of my glute swells up, raises about 1inch high and the circumfrence of a soft ball. Its not an infection, just a big knot. The last one was 2 weeks ago and took about a week to go away, after putting ice on it everyday. I know that I am injecting correctly, been really sterile, and used the same source for my gear. So am I heating the gear up too much? Is this my body not agreeing to the tren ? Anyone else experienced this? I searched the forum first didnt see anything like this... thanks for any help/suggestions...
