Tren cuts due to other mechanisms, that's a separate issue.
It still comes down to diet. Some steroids bloat and some don't. Those that don't are thought of as "cutters" but nothing will cut if you eat sloppily. As far as giving the appearance of leanness, I'd say Masteron is king because it makes you very hard and vascular, but you have to already be lean. And the effects of Masteron are very temporary. Primo on the other hand will build lean tissue without bloating.
