Is my tank cycled?

Ammonia 0 Nitrite 0 Nitrate 50 5 weeks fishless cycling with ammonia . Do I still need to dose it with ammonia and wait 24 hours to ammonia and nitrites be 0 ppm ? To be 100% sure it’s complete ?

I'd say you're done but no harm if you want to be 100% sure.

The "dose and 24 hours to zero ammonia" is the typical formula. It certainly wouldn't hurt to take the extra day to be sure, but with zero ammonia and zero nitrites, I'd say you were probably ready for a major water change to lower nitrates and ready to begin slowly stocking with fish.

I dose it 2x already with ammonia and didn’t go to zero ammonia next day . Should I still change water or wait ?

I'd give it more time then. If it was two days, maybe...
