Must Be ** D-Bol, yes you do want to split them up. Best thing you could do would be spliting them into 5mgs each,,, but that will be pretty impossible considering how small the tabs are and trying to split them in so many ways.
Another thing is you probably don't need to use a full 50mg a day I used 25mgs a day for weeks 1-4 and I did just fine. Also I don't know if ** D-bol contains 50mgs so who knows how much you really need, I've never used them myself so I can not comment.
I personally would cut the pills into 4's and if possible cut the 4's in half,,, if that is not possible though I'd take 3 of your 4's each day a few hours apart.
It all really depends how you react to the D-bol though.
If you are planning on taking the full 50mgs for the day than yes split it up.
