Look, I see things a bit differently, Taking Steriods isnt the only option you should think about, look into different over the counter products that can help you in bulking and cutting too.
But if you are still keen on taking them, do your research and when you think you have researched enough, DO MORE research. Everyone has their personal opinions on steroids, especially the ones who take them, So if they do tell you which ones they are taking, just keep in mind that it is their personal experience on the steroids they are taking relating to their own body, it might be a different experience for you altogether. Be responsible and know when stop.
I hope you find what works for you.
