My experience with ment, I can add more size/mass than I can when running tren-a. Tren-a I use more typical for leaning out/cutting and getting ready for summer weather ect (of course can still use it to bulk), while Ment I'd use more for bulking and trying to gain size/mass but that's not to say you can't use ment to cut as it builds/retains muscle very well. Although, Ment can (and most likely will) come with a cost of high estro and gyno flare ups. This can be a given depending on how you respond or how you're running your ai with it. I'm not really one to go off whats on paper for anabolic/androgen ratio but the ratio for Ment truly is on par for whats on paper. It's up there HIGH. You'll gain some strength gains like you do with tren. Some guys love it and others hate it do to the cost of sides, gyno being the biggest. I think I can recall flares up within the first 1-2 weeks of first using it. I've only used ment attached to acetate ester only and never with it using a long ester, as I've heard that ment attached to a longer (decanoate ester) has less sides=less estrogen/gyno. Would I use it again? Possibly, as I've seen it a lot more common nowadays and makes me gain a interest to at least try it with the longer ester attached to it.
