Use a pre-workout when you need a boost, look for a fairly price one with some creatine HCl, beta alanine, and caffeine. You will build up a tolerance, but it's unlikely if you're not using it every single day (Do be careful though, next thing you know, you will need pre-workout just to sit on Sythe and focus LOL). Many people advise against 'pres', but they're pretty harmless compared to hormone stacks and other performance enhancing drugs.
Then get a standard whey protein to consume within 30 minutes of your workout. It may take some time to figure out which flavors/brands you like the most. Try not to overpay on those fancy GNC supplements, since it all comes from isolated milk proteins anyways. Make gains, get hoooge.
Also, if you decide not to 'supp', then look into drinks like kombucha and other fermented foods that will naturally give you an energy kick.
