None necessary but you can run something like Lean Xtreme afterwards. I have seen a lot of people recommend this.
The product shouldn't be capable of suppressing you enough to require PCT, especially at the recommended dose. If you are doing your own thing and dosing way too high though you might need to do something as a PCT.
Really though, even if you don't need LX afterwards you should run it anyway because LX is one of the best products out there imo.
