Depends. It would be subjective like a lot of things and depend upon who was taking it and how much exposure to sustained, serious training, they have had.
It sounds like you know your way round the gym and the fact that you are competing probably means you've been training for some time?
Listening to people talk anecdotally about their experiences, some who have not had much exposure to serious training and jump on ahead of their peers can experience exponential increases in strength as they've yet to hit their natty threshold anyway.
Given you're more likely to have hit your natural 'plateau' , or are maybe at least finding it harder and harder to add weight to your lifts, the increase in strength may not be as 'explosive' as you think. Enough for new PR's for sure, but you wont necessarily be busting down doors anytime soon.
Again, it's all subjective and dependant upon the individual and where they are at + how they respond to AAS.
And the fact that you live in whoop whoop does not necessarily mean you can't source the gear.
