masteron by itself will not go well for long.3weeks and then will feel bad without bit test.
tren is better than mast insofar as it gives better fulness and more growth.
strenght increase are comparable, mast will give kinda stringy dry look, tren will give fuller look,without the stringly.
the combo of them both would seem like the ultimate stack on paper.
some 15 yearsa go i ran tren,mast ,winn,halostestin, and a very short test ester,well needles to say that felt great,lol.
but on topic, tren will give better gains, seemingly even in severe caloric deficits, while mast wont do the same even when eating slightly more.
id class mast are the most radical ped for dryness, actualy need some carbs to get somewhat full on that.
on paper, tren should be easier on the hair too, maybe some ppl care for that.
me personaly id always prefer mast over tren.
and maybe fatloss can be better on trenor seem so, but mast gives drier look.
some say tren doesnt store water, but the muscles always spill a little bit, this dont happen on mast.
they both terrible on lipids, mast being strong front runner lol.
they both best for last few weeks of contest prep imo, while tren is more versatile can be used for growing a bit.
but yah ,nothing comes close to some combo like winny+mast when it comes to grainy hardness imo.
