I started injecting in shoulders Thursday of last week. The first day I injected 100mg in each shoulder for a total of 200mg with a 27G 1/2 in. My protocol going forward is going to be 50mg every 3.5 days in shoulders. I started that yesterday afternoon when I injected 50mg in my right shoulder. My next injection will be Thursday morning. I've been on test one time before at Low T Center. They started me off with a saturation dose as they called it with 200mg. I immediately felt it kick in the first day. I had major energy and my sex drive was off the charts. Then they ran me at 140mg a week. I noticed major changes in body comp, sex drive, and mood. This time around I've noticed a decrease in sex drive. My energy is down and I feel like I have the flu. I feel like my whole body is inflamed. I want to sleep all the time. I'm wondering if injecting in glutes was better at getting the test into my blood stream? I wonder if injecting in shoulders is not getting into the bloodstream, but instead it's flooding my lymphatic system and making me sick. Also, I think Low T Center uses Depo Testosterone and I'm using the generic Perrigo from Wallgreens. Does anyone know a reason for the drastic differences in how I'm feeling between the 2 protocols? Thanks for any responses and help.
