I'm currently running a cycle of Test E QV @ 500mg wk. I'm into wk 4 and I started using Letro 2 wks before cycle started. Running Letro to stay dry this cycle. Letro dose has been .5 ED. No joint pains, but I feel so fatiqued. I train 4 days a week. Diet and calories are no different than any other cycle I have run. Usually by week 4 into a cycle Iam really revving intensity wise. Any one experience this fatigue using Letro through cycle.
