I already took of the cranks and the bottom bracket, lubed up the threads, spindle and everything and its still there. Only happens when im putting down some serious power, doesnt matter if standing up or sitting so its not the seatpost…
Can somebody help me identify the source of this creak? I'm losing my mind.

Check whether the cassette is tight
Sounds like the bottom bracket or the pedal bearings. start to change the pedals and if that doesnt help it might be the bottom braket
Did you check the headset? My stoic recently started making a similar noise.
If you have chainring bolts, check those.
Bottom bracket creaking is often confused with seat post creaking.
Check if the back wheel is firmly tightened.
Seat post, stem and handlebars, pedal spindles, chainring bolts, cranks arms, bottom bracket – check and re-grease in that order
Oil your knees
Ah good old creak searching. Not so fun. My best advice is try to isolate it as best as you can, while riding the bike that’s almost impossible to do. You can put the bike in a stand/ upside down and see if you can recreate by just applying sideways torque to the cranks to see if you hear anything. You can also remove the cranks and reassemble them outside of the bike then use a vice/ other creative methods to see if the issue is with the cranks itself, pedals, or Bb. This is if you suspect BB creak. Otherwise as others have mentioned seat rails are notorious for sounding like Bb so make sure to isolate that. From there if you only get it while applying torque while pedalling it can still be a number of things, sometimes the derailleur is not on quite right and that can cause some noise. Hub/wheel bearings and torque can play a factor though a bit less common to be quite that loud. Goodluck!
