Seriously there is not enough information to answer this question.
What was the recipe, mash profile, when did you rack it to secondary.
First, MOST stuck fermentations are not stuck fermentation, they are finished fermentations. Nothing will change this except enzymetic activity (beano, I don't recommend)
The ONLY fix, other than prevention, to a true stuck fermentation is the addition of a working active yeast population, think of a growler full of yeast slurry.
