This guy @Ricky10 is NOT just taking caffeine I can assure you. His daily stim intake is probably enough for 5 people hahaI would say with something like dmaa/dmha, you'll probably end up having your normal blood pressure, whereas if you just had some caffeine, you will have lower blood pressure than normal. Then after taking tadalafil daily for a week, some of the sides go away, and you get used to the lower blood pressure.
