I've been on various GH's over the past 3 years nearly non-stop from 2 up tp 10IU per day. I use to get the typical numb hands while sleeping, throughout the day, a little bit of water retention. However, I've swapped another board sponsor HGH for the past year, and same sides, less water retention, good body recomp. No Biggie. About a month and a half ago, after taking only 4 IU's of the grey tops, 30 minutes after the shot, I would get pretty nasty chills and shivers. My body temp seems to drop, my feet gets pretty numb cold. I cna stack on the heating pad, extra blankets, hot tea, my body will shiver literally shiver uncontrollably for 30 mins until the shivers slowly subsides. This has happened consistently for the next several sets of shots. I decided to drop the dose to 2IU once every other day, same outcome. I know it's not hypoglycemia because I get clammy and cold from experimenting with slin. Anyone experience this or have a remedy? Thank guys.
