Caffeine Crosses The Blood Brain Barrier T-Shirt
If you drink beverages with lots of caffeine, you might know this fact about caffeine -- i.e., that the molecule crosses the blood brain barrier, which, of course, is why you can quickly feel the effects of caffeine after intake. Make others do a double-take with wry scientific chemical molecule humor with this educational caffeine molecule tee the next time you go out for a jog!

Have had Zazzle complete a number of T-shirt projects in the past. This one had several design elements. It was well done. I will work with Zazzle again.

The T shirt seems to be made from decent material but appears to be an irregular t-shirt sewn and stitched. .
