Training Experience? I'd expect about 5 years of solid serious and educated lifting out of someone, before they decided to venture into steroid use.
I don't see how someone can plateau in 5 years since they started lifting, and if they say they have, they just aren't willing to go that extra step.
EVEN MORE IMPORTANTLY than training experience, you should have an extremely good knowledge of all things steroid related, before deciding to do a cycle.
Don't start researching 1 month before you plan to do your first cycle, start researching 1 year before you do.
If you've planned for your first cycle to be even 3 months from now, and your still asking on anabolicminds forum what ancillaries to use and at what dosages. Your not ready for that cycle.
I'm not saying any of this is you, not at all. These are just things you should keep in mind. Venturing into steroids is a serious step, with serious consequences for those who are not 100% prepared. Yes, a few people have the genetics to luck through life without ever having to deal with these consequences, but the majority of users aren't this lucky.
