its still a tab...cut it into 4r's. Just because the dosage is only 25mgs it doesn't make it any different than a 50mg tab. Cut it into 4r's and space them out.
Since your planning to only take 25mgs of dbol then space it out 4x's a day. The half life of dbol is only 3-5(6) hrs. So to have that even consistancy in your blood it needs to be evenly spaced.
