it's only been a few weeks bro, keep the primo at 400 and run it longer.
i had amazing results from 400mg week, but i'm a small guy.
i would DEFINITELY do another primo cycle.
i wouldn't cycle it with dbol though, stick to gear that wont bloat u and remember why you're on primo to begin with. to stay lean !!! maybe some var/winny or eq.
eq/primo a dream cycle for me.
