VERIFIED OPINION
SMART CAFFEINE
Good alternative
I use it for days when training is less intense or I just want to clear my head a bit for work or other more prolonged activity such as cycling, hiking, etc. .... I have a low tolerance to caffeine and 200 mg of a standard intake I notice it quite a bit.
