Hmm... I've never heard of a sticky batch. Do you mean actually wet and sticky or more kinda clumpy? If the latter than I suspect it's probably the newish batch that's doing the rounds. I'd say the effects are somewhere between those of the tan and white - slightly mellower and less tweaked than the white but without the euphoria, clarity and hypersexuality of the tan.
The effects you describe I'd say are broadly typical of MDPV in general but sound most like the new beige batch I mention. The white tends to have more strong negative effects than the tan but the dose you mention fits better with tan. Of course some folks are more sensitive to it than others which may explain that.
Bear in mind that it will be more intense snorted than orally dosed but even the most potent MDPV is quite safe at those levels. GBL really helps with the jitteriness and anxiety that can come with peevee as you noticed.
Well, the color is definitely beige, it's much darker than caffeine freebase under daylight. I would describe it as clumpy as you said; when I press the powder with my fingertip or something like that, there are about 0,2-0,8 cm sized longish and thin ledges/cakes/tiles (dunno what english word fits the best... feel free to correct me, would be nice

) that gets cracks when I bent the bag backwards...

This morning at 8:40 AM when I prepared a line of +- 0,5 mg 5 mg of peevee, there were some chunks that sticked to my small scale "pinchers" when I tried to break them.
Have taken 8 mg MDPV rectally + 1,6 ml of GBL 20 minutes ago after the 5 mg Peevee this morning. Onset was quite fast, about 6-7 minutes, the body load is great, my heart is racing and my mood strongly elevated, focus seemed to be already worse, was very fine this morning, furthermore I am a bit restless in my legs, strongest in my jaw (but no bruxism), good alertness.
This morning and till 1 PM the "jittering" was moderate, not stronger than yesterday though (no paranoia, more like a "natural"
coming down with some cardio-vascular issues like tachykardia...), GBL again helped a lot and I wouldn't dare to take such a dose again or more in a row without a benzo/GBL (250 mg phenazepam + propylene glycol is coming

)
What do you think would be the best for coming down and as a sleeping aid? Promethazine? diphenhydramine? pipamperone (typical antipsychotic)? Risperidone (Atypical antipsychotic)? Or 12/25 mg atenolol (betablocker)? Have read some confusing shit concerning beta-blockers though (might even worse amphetamine tachykardia or hypertension, because stimulants allegedly affect the a-adreno-receptor... but still helped very well for cardio-vascular effects of Dimethylcathinone and 4-MMC).
Regards! Gotta get out now, sitting is uncomfortable!


. See if they're some psilo mushrooms, only found three yet, anhydrous about 250 mg!
Ahh, to mention it, I had strong pain today again. I have chronical pain and have been taken 2-3 x 100 mg tilidine for 1,5 years (= about 2-3 x 20 mg morphine, only opioids and gabapentin helps, but there're bad side effects, looking forward to try pregabalin...)
