I'm sure it does on a systemic level, I just don't seem to "feel" it working. So I don't bother with my caffeine intake much. Never experienced jitters or crash even on that dose.1g caffeine does nothing for you? That's intense. I'm afraid of 400mg or more in a pre workout. Have you tried stacking Teacrine with caffeine? It's a great synergistic stimulant stack.
Considering a low dose ECY stack (caffeine and yohimbine coming from the Red capsule Hydroxy) for the remaining 8 weeks. But wondering if it would give me a significant enough boost in my recomp to be worth it ?
