Most anything with L-Dopa i say cycle don't be using for an extended period of time. And i'm tired and don't want to look it up but large amount of B6 i thought with L-Dopa is bad news. I'm sure someone will correct me if i'm wrong about this. Don't know how you dose your HGHup and IGF2 but just food for thought. Didn't think about the Huperzine A in HGHup good catch on that.
