I (24M) have just started working out need help with which protein should i go ahead with I tried to do some research but ended getting more confused as there is whey/isolate/ combination of both and what not.
I am not really what would be the right one for me. I work out around 3-4 times a week 45-60 mins per session and I am a vegetarian. Would really appreciate if some could help me with some suggestions.

I am okay with spending around 3-4k a month.
