I wanted to update this since I figured out the problem.
First, the anxiety and feeling like I was going to die was from my anavar. It was junk var.... Probably got clen instead of var, as the sides were all typical of everything that people say about clen. I'm actually probably lucky I didn't have a heart attack because I was taking 50-75 mg. I have no idea how it was dosed but it was the culprit. I used a different source for the var than in the past, so I thought that the test prop or npp was to blame.
Next... I absolutely cannot inject prop into my quads. Gave up on that. 50 mg was crippling me for 2 weeks and looked swollen, red, and as if my quad was infected. NPP turns out to be painful but tolerable in the quads. The test prop actually doesn't even hurt in my delts or glutes but it destroys my quads. Not sure why its like that.
So, I learned a couple lessons. Specifically, don't add too many new compounds to a cycle or you won't know what is causing sides. I also learned that rule also applies to the supplier. Don't add a new compound and a new supplier. Compound "A" might have worked in the past but a new supplier might sell you garbage and then it's hard to tell which compound is causing problems until you figure out that you got junk that previously worked fine. Last lesson, if you're getting bad sides, just quit your cycle until you can do it safely. I should have quit sooner. I will never try to tough it out again. Health risks aren't worth it. I felt awful for 6 weeks and had terrible palpitations- it was stupid.
