Me personally i would taper off. But its a mental thing for me. I mean id rather go from 5iu per day down to 2iu per day then stop. But again its just mental for me. plus i ran hgh straight for 8 plus years and then abruptly took 2 years off. i didnt taper off at the time and i had huge inflamation problems in my shoulders and upper pecs three months after stopping. was like my body lost its ability to heal. Im thinking it was a side effect of coming off and it put me out of commission for 6 months till it got better. i couldnt even sleep the pain was so bad and had to work out just legs and abs for 6 months. And its personally why im never coming off hgh unless something happens again where i have to. never had issues like that inflammation until i came off hgh.
