I make my own PWO. It's WAY cheaper. This is what I have in PWO mix.
Betal alanine ~ 4-6g If you don't like the tingling sensation don't take it or take less.
Citrulline malate ~ 6g
Taurine ~ 2g
L-tyrosine ~ 2g
Salt however much you like.
Caffeine and/or another stimulant that you like.
If you want to take caffeine but don't like the jitters, get some l-theanine 200-400mg is enough. I get l-theanine powder its way cheaper. You can also take this post workout if you want to chill after taking the caffeine.
Other supplements I take:
Whey protein
Maltodextrine (post workout)
Creatine monohydrate (4 weeks on 4 weeks off)
Codliver oil, 1 tablespoon
Vitamin D, 5000iu
Vitamin C, 1g (joints don't hurt as much)
Sometimes I drink about 1 tablespoon of applecidervinegar before a meal.
I'm thinking of getting zinc and magnesium.
