Uncle is certainly right
I mean, with 300mg you first experience a pleasure muscles-melting fading into a totally relaxed state, after 30-45 mins the second stage kicks in, you may feel sleepy for 10 minutes and a bit dizzy, but the concerns are washed away from an orgasmic warm propagating into your body, like the best of opioids' bliss. But, without any annoying nodding. When you believe it could not get any better, after 60-70 minutes the last stage kicks in, topping to your perfectly physical well being, a very moody, gentle euphoria - cozy stimulation complete the circle, reaching the most desirable state a drugs may offer (unless you seek psy/dissos effects, obviously). After 3 hours or so, after spending the time in nirvana but with a very lucid, entertained mind - without waking up in another room like it easily occur with benzoblasts or strong opioids, you can go sleeping and have the best sleep you could remember, waking up fresh and totally satisfied from the experience.
Uncle probably could have told stories about something even surpassing the heavenly experience of MQ, another class nowhere to be found anymore, except for some near-zero recreational usage - adding to the MQ'sque experience, an extra on-set first 20 minutes giving a spike of euphoria and stimulation like the best of cocaine and purest amphetamine combined - before shifting in the other 3 phases described above.
Currently I am very busy IRL, but I'd love to talk more about such topics - Ideally should be on a private group?
To all other readers considering MQ analogues: do whatever but stay away from NMQ, it could really give you a free cancer (not that it WILL certainly happen trying it one, but still, between the toxicity and the unknown "how much is too much to get a mutagenic effect", other than not being like the real MQ - is not a risk worth taking. MMQ will give you convulsion with > 40-50mg, I would not advice such experience either. And if you find somebody claiming to have the real thing and you will buy, send it to lab test for your own safety. Please stay safe, such compounds beauty could be lethal for several different reasons, and they are not to be considered like "RCs" of other well-known classes.
