Creatine Help Needed

Hi all,

I'm trying to ensure I retain muscle or can develop more muscle, whilst working on fat loss as well. More fat loss. Only on 20g carb a day - 3g already goes to my protein shake.

I'm currently taking phd diet whey. But also want to look into whether I should take a creatine supplement as well - is there a bad issue with water retention when doing keto for weight loss? What do you think?

Which of these 2 would be best?
