There is no question, however, that steroids can only give so much because they borrow from what you already have ,and there can be many side effects from the use of steroids. The damage that can result from this is a very good reason to think long and hard before deciding to use steroids.
One has only to look at the highly publicised cases of some high-profile individuals to see what damage steroids can do. More than a few pro atheletes have died from the side effects that the use of steriods can cause.
In the end, it ia personal choice of each individual if they want to use steroids to get the boost that takes their training to the next level. But ask any doctor and they will tell you that there are huge downsides to relying on the effects of steroids, against a short-term, superficial upside.
