I was told I should take this in the muscle in my arm instead of the fatty tissue at my stomach. I have been taking somatropin 2 IU's daily and the nutropin was suggested. Any thoughts. I workout some but not heavy duty, I use this as an altenative to taking Parkinsons drugs. I have been on somatropin for several years now and it has helped tremendously. I have been downgraded from a late stage 3 to an early stage 2 parkinsons.
