I have used c4 pre workout for a while and did like it but recently decided to make my own pre workout. I researched a decent amount about different ingredients and purchased a few from powder city to avoid a 'proprietary blend' and to save money. Here is my current pre workout stack: 6g Citrulline Malate 1-2g L tyrosine 1g Alcar200mg Caffiene
What does everyone think about my concoction?
