Best solution for you would be to try Smash amf peach mango flavor and then anything even remotely peach mango flavored will make you gag and be forever ruined. Well that was my peach mango experience anyway

Smash has been my favorite go to pre, to the point I have a ton of heavy hitter samples such as lava that I have yet to try because it’s such a gamble on a potential waste of an illicit day vs something I know for sure is gonna give me what I need and have long lasting clean energy with no downsides.
