Side effects are very individual, that is why the most important thing is to learn your own body. I constantly hear guys saying that fina kidney toxicity is a myth. It may be for them, but it is certainly not a myth for me. I have tests done that confirm fina to be the worst aggressor on my kidneys out of all the AAS I've used. In fact, I can't run it past 4 weeks because my kidneys start screaming with pain. For this reason, and many others I will probably stay away from tren.
