Hey everyone, I'm just wondering if anyone here has experience running Marathons? I'm not looking to get bashed for asking about long distance running and anabolics, just looking for advice and anyones experience. I know there are certain anabolics that runners stay far away away from (aka tren) but curious what you guys have had greatly increased your long distance endurance with and which else have really brought you down. This is out of curiosity and expanding my knowledge. I'm not looking to start a bunch of random cycles and run a marathon, just sometimes when im running and get around that 12 mile mark I think to myself, "This sucks...I wonder what kind of impact different cycles have on these already horrible runs".
