If you test positive, then what?
WADA rules applies.
You're banned from all WADA affiliated gyms, clubs and training facilities globally for 2 years.
I think, but this I am not sure of, that you will receive an automatic 4 year ban the second time caught (may be longer). And an automatic lifetime suspension the third time?
This could be wrong though, I know it applies for competitive athletes, don't know if it is as strict for non-competing recreational lifters.
