Hey guys ,, question ive been on hgh for last 12 months 6 moth on 6 month off . I currently started a new stand and i always used somatropin. New batch has blue tops and company kei-fei i believe spelt right. My current issue is that every place i inject it gets lumpy and or sore to the touch. Im very confused as to why never had problem before. I was thinking maybe allergic reaction because never had issu before ? Any advice or similar experiences? Thanks
