I personally have and will never use clen again. The tricep cramps were crazy painful. I think there's better stuff out there for sure like lipo 6 black stacked with some green coffee been extract or ephedra.
don't cut corners when it comes to your pct bro. I would also go with some pharm grade stuff with some high quality otc supps like unleashed, hcggenerate, and formastanzol.
