how long is the high?
Longer than Ritalin and much stronger. I would say the intense excitement starts at about 20 minutes after you take it and lasts for 3 maybe 4 hours, then comes a phase of another 3 to 4 hours where you are not excited anymore but feeling very, very happy and alert, and then comes the crash which is pretty bad but not as bad as cocaine. The crash lasts for about 6 hours. You return to normal about 8 to 12 hours after swallowing the pills.
when does it peak?
I would say about 2 to 3 hours latter.
how does it differ to coke?
Much more energy and excitement, but coke gives you a more "clear" high where you can enjoy music, talk and whatever you are doing more. Meth feels more energetic and excitement, but it makes you edgy and not able to focus on enjoying any given thing as much.
have you tried training under it's influence? if so, how did that go?
Nah, man. You can seriously burst a blood vessels if your train under the influence of this shit. I have taken Ritalin(orally) before going to the gym, but it makes you too talkative and happy to focus on your training. You want to talk to everyone around you and you think of a million plans you have etc...
