Just tried pentedrone a few minutes ago.
It seems to be much more potent than mephedrone.
I measured out 35mg. Some of that spilled into the floor.
I insufflated some of what was left - I don't know how much. Maybe 5-8mg but that is just a guess.
That produced a significant increase in energy, increased mental clarity, and somewhat moderate euphoria/mood lift.
Prior to that, my blood pressure was 135/89 and my pulse was 68.
I snorted about the same amount a few minutes later. I now have a lot of energy and feel more euphoric.
I did not like mephedrone very well because the side effects were pretty unpleasant at doses sufficient to really be enjoyable. With mephedrone, it was the after effects that made it undesirable.
This feels superior in effects. I will have to wait and see if the after effects prevent it from being useful or not.
I am going to check my blood pressure again now to see how much this has raised it. Due to it being a stimulant, it is pretty certain to increase it some.
It has been maybe 10 minutes now since the second insufflation.
Just rechecked my blood pressure. It is now 144/85. My pulse is 75. A small increase, less than I expected and within what my normal range is. Given the natural variation of blood pressure over minutes or even less, it is impossible to say how this effects blood pressure and pulse - no conclusion can be drawn from this. It is safe to assume that it does increase BP and pulse with it being a stimulant.
Primary effects are mental stimulation, increased clarity of thought, and euphoria. I feel an emotional warmth and openness with it as well. There is a pleasant feeling throughout my body. It may possess some empathogenic and entactogenic effects that are far inferior to those of MDMA. I have limited experience with stimulants so I can not rate it very well. I like it better than mephedrone and MDPV. It may be better than bk-MDBD(Butylone). I think bk-MDMA(Methylone) is better than this. Methylone/bk-MDMA is possibly almost as good as MDMA - I think I only used methylone once though and that makes it impossible to really compare those two.
I really like what pentedrone is doing, it is very pleasant. It may only seem that way to me because I have such limited experience with stimulants and I have never tried the ones that are generally considered to be the best, like meth and cocaine.
I did read somewhere that buphedrone is more euphoric than meth, but I have no idea if that is actually true. I'd like to try that sometime.
If pentedrone turns out to be a nasty substance, it will probably show its bad side when it is wearing off. On mephedrone, my blood pressure and heart rate were highest during the comedown and I felt severe and anxiety and panic with that one. I hope this stuff does not cause that.
I have a little more out that I have not used yet - I am going to use that in two small bumps/lines over the next hour or so and see where it takes me.
I also took 37.5mg hydrocodone and 0.5mg of clonazepam. I also took 10mg of cyclobenzaprine with that for a medical condition I have, but it does have some mild value as a recreational drug, at least to some people. Those have not had time to take effect yet as I just took those after the second dose of pentedrone.
