Steroids use is widespread, but certainly not total. Steroid use also carries significant health risks. Different pressures will lead to different levels of adoption - relevance to your sport, legality, and economic incentives all have an impact on how willing people are to use steroids, and how likely they are to be willing to discuss their usage. Still, this should not impact your personal decision-making too much - regardless of whether or not someone else is using, this doesn’t impact what you need to do to make progress in your own training.
