Need help making smoothie

I've been wanting to make smoothie kings Hulk Strawberry smoothie because it would just be cheaper overall then paying to on every other day.

i know the basics of what i need however i was wondering what would be the best protein powder

to use as smoothie king doesn’t actually sell the one they use.

For context,i want to use the smoothies as a strict meal replacement and not really weight gain. i’m also

intermediate fasting this month (and possibly till the summer ) so ideally they need to be fulfilling enough so i don’t starve.

if anyone here has any ideas on what to use to make the porter smoothie please let me know! all advise is greatly appreciated . i just want to know the best way to make this smoothie as similar as possible
