I've been on Testopel (pellets) for two months now. I have had some ups and downs during this timeframe, but I feel pretty good now. My weight has gone up from 200 lbs. to 212 lbs. (as of this morning) but I'm still fitting the same in my clothes. This leads me to believe that I'm gaining muscle as my lifts are slightly better now (just slightly, but there). My wife has commented on how I look bulkier in a muscle type of way and I'm seeing veins and more roundness in my shoulders that didn't use to be there. I know my squat is definitely stronger and I've been focused on it. However, I am drinking more beer over the past few weeks as well as a few late night A1 Thick and Hearty Whataburgers (after heavier drinking and partying), so I expect some of this is fat gain. I'm also not hardcore cardio like I was prior to TRT.
Vanity aside, my overall mood and libido is up after being on it two months. I also am taking daily Cialis at 5 mg which has helped huge in the erection department. I'm not sure if I still need it, but I say why eff with what is working. The vascular and mild anti-depressant effects of Cialis are overall helpful, so I'm happy with being on it.
I'm probably going to switch to injections instead of staying on pellets when these wear off, but that is still up in the air.
As others have said - be patient. Two weeks in I had a surge of energy and mood that promptly cratered two weeks later and I felt like shit and became somewhat desperate feeling. A couple weeks after that things were looking up, and now I feel fantastic.
