This came up in discussion a while back.
I actually stacked epistane and var in January. Was on an aggressive cutting diet, lost over 1.5” on my waist with no change in weight. Felt like total **** though, so didn’t run as long as I wanted to.
Epi tends to make a lot of guys feel crummy but I’ve never heard anyone say that about var. Epi is likely better for mass, but var is known for fat loss and being mild and easy to handle.
