i swore i had tha same headache for 4 weeks strait tha first time i used dbol....i took hawthorne berry, garlic extract, some prescribed blood pressure meds almost EVERYTHING and that headache persisted....eventually ended up dropping it....the worst was when i was squatting and i felt like someone was going at my skull with a mallot during and after the set...it was gone after i dropped it so i attribute it to that...weird thing was my bp was 180/90 at the end o week 4 n i thought o ditchin the entire cycle but it went down rather quickly after that....i practically lived in walmart at tha blood pressure monitor lol
