Gas Drop Recommendation

Charry • Can't wait to meet my Greek/Hungarian-Filipino Baby Boy!
Hello Momma's! My baby is 1week1day old, breastfeed but still seems to be gassy. I always try to burp him but it doesn't really help so I am looking at gas drops but I don't know which is the best one to get.
Anyone who could suggest me a brand? Or share their experience in using it. I would really appreciate any help.
