Testosterone help

Patient: I am a 47 year old man who is gaining weight, lack of energy, can’t sleep and my erections are definitely not as strong as they were. I was going to go to a low t center, but insurance doesnt cover. Is there a supplement that I can purchase that will help increase my testosterone to a stronger level ? There are so many things in vitamin shops that I wouldnt know where to start.

Symptoms: lack of energy
weight gain
lack of strong erection
