What dosage are you on? It's hard for me to pinpoint exactly how each part of my stack is affecting me, but I definitely feel some impact. After five weeks, my muscle is increasing noticeably and I'm getting a bit leaner each day, though I'm still far from lean at 6'4 and 290. The biggest change is faster recovery from daily lifts, but I can't tell if that's from the TRT, the Klow, or the IPA. I feel much stronger than expected for someone my age of 56, even like a 20 year old. Energy is much better compared to a year ago with nothing. The only negatives are higher blood pressure and resting heart rate than usual. I think the BP rise comes from longer-term weight gain plus some temporary water retention, like the 12 pounds I added in two weeks at the start, which has since disappeared.
