Sorry can't help with Gain.
Do your friends live in Pinas ?
Almost all the folks I know here send UK Baby Milk powder to Philippines as they swear it's so very much better.
Personally I have no idea about such things
Lol! I'm the same as you, no idea about these things! No, they live here in UK.They wanted me to bring some back with me when I was in Phils, but I didn't have enough room and already had to leave some things behind!
