The "
Test Flu" is fairly common, but often the symptoms you're describing are caused by gear that contains a high bacteria count. What brand of
Test and Deca are you using? Also, I would agree that you might want to lower your
Test dosage to 500-600mg EW (especially if this is your first cycle in 2 years). As for being sterile, after 3-4 weeks of taking
Test this does occur in over 90% of men, but personally I would never take the chance. Go to your doc and get some lab work done to make sure.
Good Luck!
