hgh headaches

I am getting headaches from taking hgh. Blood pressure is 119 78. Blood glucose is normal last time I checked but I'm going to buy a blood glucose monitor. Could this just be due to the brand? Has anyone else had this problem? I respond very well to gh but I can't use it if it keeps causing headaches because I work in an intellectually demanding job.

The headache started after my first dose of 2iu pharma. It feels like a pain on the forehead/sinus region. I have a bunch of gh that I need to use but the headaches are ruining it for me. I respond quickly so I would love to keep using it.

What brand are you running?

Are you eating directly before or after you inject?
