Creatine is pretty much all excreted out via the kidneys and Trenbolone is the only steroid known to affect the kidneys and just cause overall adrenal impairment while it is being used. I'm really wondering if it si possible that take together both can be damaging to the kidneys. Creatine shares synergistical effects with steroids like anavr, but Trenbolone the interaction might be too much. opinions please guys.
