Skull......
I don't like to review supps... Not everything works for everybody. I mean I have a high tolerance for stims 🤷🏾♂️ anyway.... THIS RIGHT HERE!!!!!! Taste great, dragonfruit is sweet not sour 👏🏾 here's the protocol PB & Rice cake first with Skull Wait for 30mins.... Tunnel vision, great energy, good pump. No crash!!!

Needs a boost
Are you looking for a pre workout, that gives you no energy or pump? Then this is the one for you! Don’t worry though, it will still give you the feeling of having a mild anxiety attack, while also sweating puddles.. Kinda tasty when mixed with carb powder though
