Where to buy energy bars in ho chi minh city?

Hi,
Do you know where I can buy energy bars in saigon ?
I mean the kind of candies with a lot of calories, for runners.

you can try the GNC stores, there are quit a few now in Saigon. Just google there locations in VN.

I have no ideas about this candies but seems it is imported products, you can find it in Ben Thanh market or Ham Nghi street.

Vietnamese energy bars are everywhere in Saigon.  They're called banh mi.

Gnc stores look perfect thx.
