exactly 4 weeks into 500/wk test E and i have NOT been feeling it lately. It took effect pretty quickly at first. After a week, maybe 10 days, i could feel the mood-changing effects, and my strength improved fast. Added another rep to practically every exercise every time i went to the gym. That lasted about 10 days or so, then suddenly i got weaker. My reps actually dropped by 2-3 on most exercises. This is very weird for me. If my reps drop by even one on more than one exercise, i know im having a bad day. And it's always better by the next time i get back in the gym. This has lasted about 10 days. I think i'm doing less than before i went on cycle for most exercises, or have at least lost the improvements i made in the second/third week. I'm not using an anti-E, could that be a reason?
