I believe you mean "Clen" tabs. Im going to assume also that the clomid is being used during your post cycle recovery.
So to answer your question, sure, you can use Clen tabs during PTR. Clen is anti-catabolic so its not gonna hurt. But there should be a purpose if your wanting to use the clen and that being that you really want to lean out. Consider that your gonna lean out quite a bit if, during your cycle, you were taking any gear that made you hold water. The water will leave, thus leaning you out a bit and then if you throw the clen in the mix (keeping your diet in check), you can expect to lean out nicely then.
