This reply may piss someone off, but I have to remind people that BB (bineural beats) have so far not proved to be working, let alone make anyone gain inches in a few weeks.
Apart from, maybe, inducing or being part of a pink fog that may make you think that you are growing, there has never been a user who posted before/after pics showing growth from BB alone. On the contrary there have been spammers who posted here links to their channels of useless noise just to gain new likes and thumbs up on social media.
That said, regardless of your method, if you go through budding and build up actual breast tissue, that will remain after you stop taking or doing what you are taking or doing. If you only built fat deposits, those will go away after you stop, and after blood circulation in your chest area decreases.
