LIPO C, FAT BLASTER or MOTC?

Hi there pepbuddies. I want to stack one fat burning peptide for my stubborn fats since I'm so big, I really need this one. I'm currently using tirz and ghkcu. I am not in plateau state since im losing 5kgs in 6 weeks but is not visible in my appearance.

For those who tried these peptides, can you suggest the best one for me pls? And also is exercise necessary while using one of these peps? Kindly help, i still have a very long way to go before i slim down. 🥺 thanks much!
