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.

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.

Aggregated from 10 Erowid experience reports
Each bar shows the share of analyzed reports whose text mentions that effect — a mention is not always a first-hand experience (fear of an effect, something witnessed, or "did not happen" count too). Tap or hover any number for details. The second value is the Bluelight extractor's per-effect confidence; a dash means the row is Erowid-derived, which has no confidence measurement.

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.
