Heres my cookie cut answer to supplements, if your going to spend money on this shit might as well get products that work.
During workout or Post workout and on Non-workout days:
Creatine Mono 5g's (preload at 20gs for a week)
WMS 40-50gs (chalky texture, if you cant handle the texture go for some maltodextrin or dextrose)
BCAA's 20-30 g's (if you can afford it, if not 20-30g's of whey would work)
Through out the day:
Beta Alanine 2g's 3xED (give this a few months run before discrediting it)
BCAA's (at times of fasting or long periods of activity, if money is an issue could use Leucine)
MRP (if your need it, of course whole food would be best):
3/4 cup ground oats
20 g's
Egg Protein or Gemma Protein (tastes like shit but can be covered up in various ways)
Everyday Supplements:
Multi Vitamin (depending on how your diet is)
Fish Oil ~3gs
Simple and affective buy everything in bulk you'd be amazed at how much money you will end up saving. These are supplements... just make sure that, thats all they are doing... suplementing... dont use them as a cruch.
