do some googling and see the timeframe most are reporting for starting to see the shots taking effect. you will find most reporting 3-6 weeks for various benefits, while others not becoming apparent until 12+ weeks (body composition).
I am new to TRT myself and not familiar with Testoviron, so maybe it’s some fast acting Test I’m not familiar with, but my understand is you aren’t going to go from feeling like a like of crap to feeling great on your first shot regardless. With low T, you likely have other things out of sort, and those things will take time to adjust so that you can realize your higher T.
If you want further help, read the stickies and educate yourself a bit, post the requested lab results, etc. Your age and total T # doesn’t give near enough info for anyone to tell you anything other than “yea you have low T for your age”.
