Wonderfull Experience Today I received 1 gr. Alpha php and it was a pleasant surprise. In the past I have made use of MDPV and now that I can no longer find, I tried an alternative not the same but at least similar: I think I have found it.

Summary
alpha-PHP is an extremely potent stimulant with a high addiction liability and significant risks of paranoia, anxiety, and psychosis. It is structurally related to alpha-PVP but with a longer alkyl chain. Users report intense compulsive redosing, especially when vaporized.

Tolerance Decay
Full tolerance

Half tolerance

Baseline
~14d
Acute tolerance: develops within a single session β the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.
Rapid escalation in a single session is common due to short duration and fiendishness, particularly when vaporized. Several days to weeks of abstinence are typically needed to approach baseline sensitivity. Data quality primarily anecdotal.

A Very Dull Double-Edged Sword IΒm writing this report quite a while after using the substance. IΒve since stopped all drug use so thereΒs probably going to be a bit of bias against alpha-PHP (a-PHP from here on out) but the description of its effects should still be accurate. IΒm no stranger to stimulants.
Subject background: - Previous experience with similar chemicals: 4-FA, 2-FA, 2-FMA, Amphetamine, Dextroamphetamine, and 3,4-CPMT. Primarily interested in stimulants for functional stimulation in school and in the workplace, moderate interest in stimulants as entactogens in social settings.
Although new to experimentation with research chemicals, I have been trying new substances since age 15. IΒm not a psychonaut, and prefer cannabis over anything else.
I have been using this chem for a while, as have many others. Due to a lack of knowledge, the decision to collect and research this chemical became quite appealing. The dosages are comparable to the previous a-PVP; yet due to its addictive nature, redosing makes it hard to set a solid dosage.
a-PHP Background: Regular weed smoker. Tried cocaine maybe 3-4 times before. I do procrastinate alot though. So I though, after reading several reviews, to give a-PHP a try to help with procrastination. First time ordered 1 gram about 3 months ago. It was in powder form.
I've used this drug in different ROAs, and will write different experience reports related to the ROA. I mostly use it to get shit done, since I have bad ADD. Oral : 20mg. I put a little crystal in my mouth, it kind of numbs my mouth, but not as bad as cocaine.
Mind altering substances were a hobby of mine. Something I did in my own room, experimenting with various substances whether they be psychedelics, dissociatives, stimulants, deliriums etc. I didnΒt mention this ΒhobbyΒ to most people I know, I like taking these substances and just seeing what happens in my room.
