I shot HGH ED as part of being hypopituitary and 1 time when I got a new cartridge to insert into my pen type device, bleed off the extra air and shot the HGH. When I looked a my pen ,I had shot 15iu's. Good thing I was going to bed cause within 15 mins I got so tired and sleepy I could'nt stay up. Staying on HGH a long time ,it will increase the size of your organs. I know because after 3½ years I had to go into the hospital and have my R kidney removed because of cancer. The Drs. operating said my kidneys had taken an unusual shape and they were larger and never said anything about my other organs. If I had to pay for it ,I probably never would have got on HGH but being a Veteran and getting it through the V.A. it cost set me back a $7.00 fotr a months supply 116 ius of Somatropin by Upjohn.
