I'm in to my 3rd shot to jintropin right now...Trying it a different way this time,..I use to get painful pumps and carpal tunnel when running the jins at 5 IU's ED. I am using the advice of a couple pro's and running higher doses of gh every 3 days. I'm using 15 IU's every 3 days...Nothing too new yet but I haven't been ont he scale in awhile and I don't have any carpal tunnel going on. Some of the guys usinjg this technique have jumped up 12-16 lbs in 2 weeks while maintaining the rest of their drugs the same. I figured it was worth a shot. I'll see if I can find any literature for you guys...
