True. I've used tri-tren by itself and didn't notice much difference between that and tren-hex. I could feel it wear off at about the same time as tren-hex by itself did- about 3 to 4 days. But I do love the "kick" you get from tren-ace; unbelievable!!! For me, tren-ace wore off in about 2.5 days; after that, I just shot up more @ 40mg each time with great results that I've kept.
