    A Weekend on Ephedrine neutral exp #41

    We started just before work. I was bored and feeling strangely adventurous. My friend Amy was having a cigarette and she pulled out a dime-sized ziploc with a lot of small white pills in it, took 4, and handed me 3. After we'd taken them, she explained that they were basically a natural form of speed.

    The first time I bought a yellow jacket, I had been in the vitamin and healthfood store searching for Stacker 3's, another ephedra loaded stimulant. I was amazed at the wide spectrum these pills were available in: pink/purple, neon yellow, yellow/purple, blue/black.

    One day I was waiting in an acquaintance’s car when I noticed a bottle of pills in the glove compartment. Being the curious individual that I am, I examined the evidence. The bottle had something printed on it about giving one energy and alertness.

    The Recreational Effects From Ephedrine neutral exp #14733

    This is not one specific experience report but rather the compilation of various ephedrine experiences and a guide for people new to ephedrine. Ephedrine can be found in OTC (over-the-counter) pills such as Mini-Thins, Yellow Jackets, and Stacker 2s.

    Yellow Jackets Attack neutral exp #79490

    So this was going to be like any other experience i've had with ephedra up till now, or so I thought. I had bought a bottle of yellow jackets in my local smartshop, never had that specific brand of ephedra before but figured it was the same thing I was used to dose wise.

    It all started a week before when I saw these really cool looking pills behind the counter at a gas station. The pills were yellow and black, and actually looked like yellow jackets. I got some before work where one of my co-workers and I sniffed one for kicks.

    I will try and keep this as cut and dry as possible so you can see how fast you can hooked on a substance, even a diet pill. I am already a skinny guy so maybe that influenced my reaction. The following took place over 6 weeks. A friend of mine started taking Ephedrine to lose weight.

    This is not going to be a very detailed report because there really aren't many details to report, however I feel I should share my findings because there certainly were effects. I obtained 3oz of dried ma huang from a local vendor. I've been looking for it for a long time, and finally found some.
