Most preworkouts for me is just a black coffee dumped with protein powder mixed in. Perhaps a bit more pricey but I'm a huge fan of «Dark Matter» from MHP, both original w' carbs and the zero carb version, either pre and/or post.
If I'm "natty" at the time, admittedly I will look for a boost as I'm missing that pump feeling; I will use a -non stim- preworkout. I don't need stims, for motivation, and I feel like some can affect the appetite which is a bad thing. To better answer ur question I've had good results from «HEMAVOL». I know alot of people which take EVP by evogen but I'm taking it now and see no benefit other than it has amino acids which in case I prefer dark matter anyway. I'd avoid the evogen brand which is way overpriced and overhyped.
-Dark matter is great for building blocks and nutrients
-Hemavol actually seemed to add a pump
(Probably should've only answered with those 2 lines but maybe you wanted more of an explanation to why I recommend such)
Best of luck with your training :headbang:
