Yes, I am having some luck now too finally. I'm 7 days into H2O2 dosing and starting to see some results. I have not done a major blackout period yet (along with H2O2 dosing I mean - I have done several 3-4 day blackouts before now). I think I may do that starting Monday. We'll see how things go this weekend but the dinos are definitely reducing now. I am dosing 1ml/10g on a 400g system and like hypr I am not taking any rocks into account.
