Can anyone tell me about testosterone supplements?

  1. How did you know you needed it?
  2. Do you need it, or is it enough to just want it? Do I need a reason to take it, other than strength gains?
  3. Is it safe? Are my balls going to survive?
  4. How easy it to get in the UK? Will a doctor prescribe it me easily or is it more difficult to obtain?

Any general information would be appreciated from anyone with first-hand experience.
