I love both of them. I love the synovial fluid from deca, and I also have good joint recovery on EQ as well. Both make me stronger, both help me gain weight. Deca is a little more potent in that regard. EQ makes me more vascular, and my appetite goes through the roof, especially at 600-1000mg a week. Both are awesome compounds.
Personally, I love running both at the same time. I like high test (1g+), moderate deca (400-750) and moderate EQ (600-800). That is my absolute favorite for meet cycles, along with some anadrol/methyltren/halotestin (one or the other lol) . I feel awesome, I eat well, I sleep well, and most importantly I gain strength at a great pace and they are predictable gains.
