I take
Fish oils: NOW Omega-3, you don't really need 6-9 because they are abundant in our daily diets.
Multi: NOW Adam
Creatine: Monohydrate should be plenty for you, if you want a bit of a more complex formula look into Universal Storm or Controlled Labs GreenMAG
Protein: Many swear by ON, but I honestly prefer Dymatize Elite in both flavor, quality, and price. I am currently enjoying the Cafe Mocha/Butter Cream Toffee isolates.
This should be a great start, and if you have any other questions feel free.
Once you get a little bit more experienced, getting closer to a plataeu, and used to your body there's some more things to look into.
Pre-Workout: Obviously, I love SteelEdge it's a sustained focus, energy combo. I have also heard matching it with RPM gives insane results.
During: I'd look into some BCAA Blends(Xtend, Excell, Purple Wraath) and add some Bulk Leucine. This can actually be sipped on before, during, and after.
Post-Workout: There's tons of options for this. The only thing that is set in stone is that it should be in water, not milk. You need 2:1 ratio of carbs to protein. I personally do dextrose and whey protein isolate. Some people like maltodextrin/dextro combo, some like palatinos. Recently WMS (waxy maize starch) has been receiving positive feedback, and I bought a few pounds of that. Really though, you have a general 30-40 minute anabolic window after your workout that you want to replenish all your depleted glycogen (polysaccharide of glucose which servers as our primary short term energy stores).
These last three can wait though, as you may not want to burn out with knowledge or cash
Hope this helps!
