Duchaine confused kidney pain with lower back pumps (water retention). Trenbolone, or Tren made from Fina has no further stresses on the body other than being a very androgenic hormone. IMO - the kidney stress being more so with Fina, or Trenbolone period, is crap...

If anyone wants to provide some actual studies other than "my kidney's hurt" to say trenbolone is toxic to the kidneys - please do. With any information as to why this may be the case...
