No doubt low T therapy can help you on the court. But its a bit like breast implants. So many women get implants because they have small breasts. But are they really 'small' in the first place.. :P
I'd also agree with the idea that low doses of steroids could have superior results because they don't have the androgenic side effects and you get the anabolic results.
The downside its probably tough to get a doctor to put you on a anabolic regimen - and its expensive. Whereas low T can probably get covered by insurance.
