You forgot about IV!
No, I didn't. Most people who have experienced this have stated it was TOO powerful, and did not desire to repeat it. IVing was a common practice in the 70's, and early 80's, and is still done in recent times. Injecting drugs of any kind can be dangerous for even the most experienced user, so please use caution, and be sure you know what you are doing before you go through with it. Please read the "Intravenous and Intramuscular Injection" FAQ for more information.
IV MDA is one of the most intense experiences you could imagine. It's not like taking the drug any other way. Some people enjoy it, while some people find it to be too intense, and rather uncomfortable. There is an extreme "rush", followed by sometimes hours of open eye visuals. IV MDA is extremely dose sensitive. As little as 15mg of variance can mean the difference between an enjoyable experience, and total hell. If you decide to use this drug in this manner, please be very careful. You must have pure MDA powder in order to do this. IV administration of pills can be detrimental to your health.
