It's interesting that you post this, as I'm noticing a similar thing. I just finished my first week of T-1 final and have gained 4-5 lbs, but have had no strength gains at all. However, last summer when I did one+ I had good strength gains within a week I think, and the same in Jan. I was doing around 16 squirts a day of one+, and 4 squirts a day of T-1 now. I think this is around the same amount of 4-ad, but much more 1-test. My gains have been fairly lean, little bloat because I've been running nolva. I am trying to figure out why there's been no strength gain yet. I know with each use of it the effect is lessened, so perhaps it will take longer to "kick in" then in the past. Any ideas?
