BUT its a pretty good fat burner that doesn't eat away at muscle . in some studies on animals Clen has shown to be slightly anabolic at most and anti-catabolic at least , meaning it burns fat but preserves muscle. T3 on the other hand is catabolic and will mobilize muscle or fat for fuel equally.
personally no I don't advocate the use of Clen during PCT (thats an old school method guys used to use thinking that Clen was powerful enough of an anti-catabolic to help keep gains while on cycle with zero suppression , but its not that anabolic at all). I advocate food, lots of food, and heavy training during PCT to help keep gains .
