Like everyone said, these are very common sides. Nothing to worry about. I myself belong to those people that analyse everything. Like temp a little high, what's wrong? On cycle usually that means that the gear is doing it's job. Also using AAS without Nolvadex is out of the question for me. I get a lot of weird feelings without it, but when i use it, i feel great.
One more thing, most people won't admit to this, but gear has some psychological effects. What i mean is, you might feel kind of weird and get all paranoid that something is seriously wrong, even when it makes no sense at all. I never use any kind of recreational drugs, but i got an prescription to Xanax just so that if i get this paranoid/weird/bothering moments because of the sauce i pop 2 mg and i'm fine again. I know that Xanax is a prescription med. and not a rec. drug. but it seems that most people use it these days to just get high...
Best of luck...
