I am taking eq now also and had experienced flu like sympotons. Every one is different so its possible. As i took more shots and the weeks went by i was getting less sick each time. I take an asprin the morning after just in case and im good.

He should separte the shots i found that helped to stop the flu like symptons. I was taking 450mgs one day(250cyp 200eq) and 300 (eq)another day during the week.
Now i started taking 250/125 twice a week and have felt a lot better. He might be getting sick casue the dosage are very high.

Another thing to the bros who responded to this post find out more stats like height weight past cycles/how much his doseages were before recomming him to take 400/500 mgs of test. Also find out the kds goals not everyone wants to be a huge or gain 20 pounds just casue u want to dont mean he wants to. The kid is a football player what if hes a is a QB does he need to add 20 pounds no it will mess his arm up. Also the kid is getting sick and people are recomming him to take more 500mgs of test which from what i hear is worse then eq in givng flu like symptons. No flame to anyone just trying to help out the best i can.
