Hi all. I was diagnosed with low testosterone by my GP and have been self injecting prescibed test cypionate IM every 4 days for 2 months. I had blood work done (thanks discountedlabs.com) to check t, free t, and the ultrasensitive estradiol because I wanted to switch to subq eod for a couple mo and compare. For IM I was using a 1" 25g needle in quads and delts, and that went fine. I tried subq in the oblique fat with 27g 1/2" needle. Injection is a breeze but I am having terrible anxiety/racing mind the day following inj. I am using the same test cyp (pfizer) and don't understand whats going on. My GP says its in my head but I know its not. Anyone heard of this? BTW, my estradiol was well within limits after 2 mo of IM inj and I am only taking test, no HCG or AI. I have labs from Sept when I was in between trt and the recent labs as well if I need to post them.
