9mg 5-meo-mipt. When I tried 6.5 it was pleasant, but seemed "not quite there". There seems to be a threshold with this stuff between 5 and 10, and at 9 I was definitely over it.
I found it to be pretty phenomenal. A lot of people seem to really love this stuff and now I know why. At the right "sweet spot" dose, this is one magical, special chemical. Closest I've come to the RC "Holy Grail." It seems to really have it all. Fast acting. Smooth really nice actually fun come-up. Low bad body-load. High good body-bliss "load".
Some have said at these levels it is not psychedelic, but that was not the case for me... I was having really beautifully animated delicate but strong trails, color/light enhancement; very blissfull mental space; morphing afterimages; quite entactogenic, too... really heart-opening and happiness-inducing. In fact I'm still feeling really really Happy Happy Joy Joy even now, 18 hrs later; powerfully anti-depressant.
Very awakening... but not terribly "tweaky"; tactile sensations were great - I've never felt randier in my life! Orgasm was amplified in length and intensity. Obviously why some have reported that there are alot of Chinese "libido-enhancing" pills which have this in them (got to look for for more info on those online soon).
Yet another nice aspect - seemed very liable and controlable; I could seemingly shift the drug's focus of impact on the mental trippiness, or the euphoric body-bliss at will.
Better even than 4-aco-dipt which I loved. That chems "magic time" window seemed disapointingly short, and made me want to re-dose. Not so with this stuff. I was good for at least 5 hours.
I felt the "second-wind" effect at the end that some have reported. Just as I thought it was about to trail off to ending completely, I got an unexpected "kiss goobye" from the substance... a final sudden hour-long wave of renewed body-bliss and psychedelic effects. A little odd & unexpected, but it made for a very very nice send-off.
Postscript: I have tried it several times since this first 9 mg experience. The "send-off re-trip" pulse was only sensed as a such a discrete event the first time at effective (9mg -13mg) doses; though every time I've noticed it really can seem to "linger" alot longer than you might expect from the quck come-up, though this does not seem to be the case with others, such as Jamshyd...
Some things, seem to have moderately differential effects on people. I've noticed this with 4-aco-dmt... same dose that is mind-blowing for one person, another says "I think I felt a little something." I get the impression these ACO and MEO compounds are somewhat finickey - perhaps due to the ACO/MEO they are absorbed and/or metabolized at greatly different rates in different people due to who-knows-what individual biochemical factors/conditions???
I have NOT tried 5-Meo-Dipt yet, but I'm getting the feeling that I won't like it as much as 5meomipt.
