i was just browsing the board and i noticed that when taking ephedra your brain receptors develop more of a tolerence to the drug. i have been taking eca for the past two years wheather it be for a preworkout buzz or an all night study session and my question is can my receptors eventually fizz away? ( i have been taking the same amount 25 mg of Ephedra, 81mg Asprin, and 200 mg Caffine, i may take this dose once to twice a day very rarely three times in one day.and i still feel a nice energy rush as i did when i first started to take these together) and one other question would caffeine alone have the same effect as eca on the receptors. thanks for any input.
