Zen Peddler Posted May 10, 2013 I am very sorry about the double post but I simply had to ask. Anyone got any experience with this stuff? I was merely trying it for low blood pressure which it helped amazingly after my body got used to it - but it has uhmm... side effects... Supposed half life is only 3 hours. So why does it work for at 6 for me? took a dose at 9pm as a top up and I was still wide awake at 4am! Im assuming its some sort of indirect agonist of alpha receptors via a similar mechanism to ephedra? Share this post Link to post Share on other sites
