It doesn't necessarily have to be high doses because a lot of it can depend on how healthy a persons kidneys are to begin with and also if there are any other conditions that may contribute to or make them more predisposed to kidney issues; like high blood pressure for example.
Of course on average, the higher the dose the higher the risk - but I wouldn't assume that lower dosing of it doesn't mean that there isn't a risk or lesser of one. I hope that makes sense.
For a long time, the risk of kidney issues was severely overlooked and I'm glad that more people are aware of it now and taking more precautions to help them with it; that is one of the main reasons that we recently made the Kidney Assist XT product, which a lot of the people here that frequent the Anabolic section really like.
