There is no way to spot reduce one single bodypart on your body. You lose weight/fat in different places from person to person
Some people can have full Abs at 12% BF, and some need to get under 7-8% to see them
Yohimbine/Forskolin95 would be your 2 best bets for Fatloss agents to help stubborn fat in general
Yohimbine best utilized in a fasted state upon waking starting at 2.5mg and slowly assessing tolerance and building your way up
Forskolin 95 dosed at 50-100mg 2x a day (Shift has this or look into Forslean)
both are great products to look into
For complete fat burners --->
AEN LIV, ANS Diablo, Norco(Since you have tried Alphamine)
These are products you could consider
Diet is the key factor, just keep dieting, over time it will come off, continue to adjust your intake, and also Cardio (HIIT may be essential at this point and time) to shed off the last bit of fat.
