I think some test boosters work if you do your research and try one out. You will know in a few weeks if you are seeing any gains in strength and muscle gains. I have tried two different products in the last 2 months, one was BRI Testrone and the one I'm taking now is called Test Worx in addition to starting DAA twice a day. My strength has increased along with muscle gains and definition.
But, you have to put in the work as Dhorv9 says and lift heavy because just popping a pill without pushing yourself in the gym will not get you the results you want , which is the same for people who choose TRT, they still have to eat right and lift to get positive results.
