For traditional TRT, aka non-bodybuilding levels of Testosterone, this is almost what we would consider the opposite. Testosterone in men helps to maintain metabolism & low Testosterone often leads to increased chances of obesity and poor health. Those issues will cause a man's earlier death more than anything else.Responsible usage of Testosterone with a dialed in range of highest benefits to lowest side effects is one of the easier ways to improve longevity in men. Every single one of our providers are on TRT for their long term health as they age. Take this with a grain of salt, as Testosterone hasn't been around in an easy injectable form forever, but everything seems to point to this being true.You are correct that harder steroids can cause more health concerns, especially abuse. A lot of oral steroids will cause liver issues or running ones longer than you should will harm your thyroid. Things like Trenbolone, which are not natural hormones, were made for cows to maintain their meat on long truck rides without food, and are illegal for use in humans. You can see why that may cause issues despite its powerful effects.
