I've been taking Ultima Enanthate 400. I administer 200mg every 3 or 4 days and I've noticed around the 24-36 hour mark after injection I feel a little weak with no energy and last night I had a fever of 102. I sweated a lot thru the night soaking 3 shirts and the bed and this morning I feel fine. This has happened twice. Does anyone know why. I've never had these side effects before and I'm not a beginner. This is my first time trying TestE. The pip is pretty bad too. I've heated it up, use a 25g 1 inch and push slow and still it lasts about 5 days. Could it be a bad batch ? After I inject I massage it alot could that be releasing to much of it to quick causing the fever and sweats ?? Please any advice is greatly appreciated
