Interesting...I felt really out of whack on 75mg + caffeine. I was really motivated within 15-20mins, and I picked up my bass guitar, and was just on fire. I even played GuitarHero 3 a lot better ( I am good at real guitar....and not good at the game, lol). I also was sweating a bit. Heated up really well. Cant remember that feeling since 9 caps of HEAT stack.

I def. crashed from it. Not so much energy-wise, but like I fried out my feel good hormones. I was going through the steps at the local bar, and being social, but I just couldnt turn up my energy. I was like BLAH...and people could sense it. Interesting. I was talkative as hell though. I think I am suffering from a lil rebound today. Im just whacked...but I am also starting a new supp. Ill have to see if it continues.

Overall...great social, motivational, type tool. Felt awesome for at least 4-5 hours. I think if I had a few drinks I would have evened back out.

Here's a link to some reports of people seeing how much they could really get out of this stuff.

I agree on the feeling a bit off in mood after using too much of this, I experimented once with 2 Caps of Amp every 2 hours one day from 7am to 7pm (because I could, thats why), and I mean, wow, great mood that day, its was a high no doubt, but I crashed that night (as expected), slept well,but damned if I was an evil angry moody man the next day...

great stuff none the less..must order more.

I have been taking AMP for quite a long time and now I take AMPv2. The thing that I really like about these geranamine products is that their effects last many hours and there's no clear point in time when you feel it wearing off. That's why your crashing from this looks so strange to me, since I've never ever crashed on this product. On the other hand, things like ritalin make you crash quite hard, but not geranamine.

How soluble is 1,3-dimethylamylamine in say water? Seems the junkies on the above link have mentioned considerable effects with low doses (5mg) when insufflated.

Pure 1,3-DAA might be a good candidate for intranasal administration.

the free base is a liquid. not much you can do with that, its very alkaline and nasty

the HCl salt is the practical form and it is very soluble in water
