Supplement recommendations?

Rosefern1

Thinking of a meal replacement/supplement for those really busy work days (12 hour days then studying) when I don't really have the time or motivation to make something. Also I have a hard time meeting my protein requirement, even if I were to have a turkey sandwich or chicken breast for dinner. Have drank Isopure in the past. Is this nutritional enough as a meal replacement? Any other protein drinks that would be a better option?
