Anavar (var) has been shown to cut a certain type of ab fat but other than that gear is mainly helpfull in maintaining lean mass while on a cutter. the type of gear is not as important as the diet and training.some steroids have a rep for cutting or bulking but most of those reps are based on if a steroid causes bloat/water gain [ bulker drug] or dries you out [ cutter drug ] . the water will either leave or come back after the cycle is over and the effect is temporary.
imo test eth or cyp with some aromasin is a great compound to use on a cutter. winnie has a rep as leaning you out but its really drying you out and the water will come back. legit primo is like the holy grail , rarely seen but talked about a lot. Anavar (var) is good in a cutter but i would still run some test with it , the same goes for tren.
