The purpose of this post is as follows, and is simple: To disseminate useful, accurate and understandable information directly comparing these two substances, applicable to the way they are typically/commonly tested by researchers. Additions to the thread that adhere to this purpose are very welcome!
's qualifications: Frequent, broad and in-depth experience with MDPV
practically since the day it came out in the early-mid 2000's, and a very recent introduction to aPVP via a well-trusted and reliable source. Thus this post is accurate but subject to additions and fine tuning.
aPVP (alpha-PVP) vs. MDPV comparison:
**These are two very similar chemicals in structure, related to pyrovalerone and resembling twin brothers in their nature, or a "female" vs. "male" mallard duck... however, they both walk, look and quack like a duck, not a duck/crow (as an example). My chemistry knowledge sucks, so if I put this funny please forgive me: MDPV has a "methylenedioxy" addition to pyrovalerone (said to be inactive), while A-PVP
is actually a little simpler in structure than pyrovalerone (desmethyl pyrovalerone, missing methyl component).
MDPV (appearance): Powdery white-to-tan.
A-PVP: Clumpy tan to dark tan.
MDPV (odor): Mild "pyrrolidine" type odor (like smelly sweat-socks).
A-PVP: Heavier (moderate) "pyrrolidine" type odor.
MDPV (solubility): Dissolves in H2O with difficulty, mild "pyrrolidine" type odor in solution.
A-PVP: Dissolves readily, heavier (moderate) "pyrrolidine" type odor in solution.
MDPV (smokeability): Vapes somewhat uncleanly, mild to moderate harshness/odor.
A-PVP: Vapes very easily/cleanly, moderate to heavy harshness/odor.
MDPV (onset and duration): Slow to medium onset of effects, lesser dosage needed, greater duration.
A-PVP: Rapid onset of effects (all tested ROA's), 1/4 to 1/3 greater dosage needed, lesser duration.
Summary (useful info):
a-PVP vapes better/cleaner than MDPV, but is harder on the lungs and harsher. Effects come on faster, but last a shorter period of time and more is needed than with MDPV for similar effects. A "rush" is possible/likely with a-PVP (particularly if smoked or injected), and unlikely with MDPV.
The "highs" are otherwise near identical (in SWIM's test subject's view) -- plain old NDRI
) reuptake inhibition and stimulation with varying/unpredictable euphoria
, an increase in sexual tendencies and unpleasant tweaking at higher dosages.
APVP "feels like" a cruder, harsher and less sophisticated (but faster-acting and smoother burning) version of MDPV. It is NOT "mdpv-lite" .. it is "MDPV fast, simple and crude".
Harm reduction notes:
a-PVP is currently (albeit iffily) legal in most places, whereas MDPV is illegal and carries risks to acquire. a-PVP is likely harder on the body than MDPV at sites of administration and may cause more damage to administer, but easier on the mind and may cause less damage due to requiring higher doses for same effect and wearing off more quickly.
A few posts on the Net have noted that a-PVP "feels safer" and more predictable than MDPV. SWIM's testing upholds this with one reservation: namely that a-PVP can still cause panic, anxiety and extreme agitation at too-high doses, just like MDPV. Don't expect peak effects to be much (if any) different. *Do* expect them to diminish faster.
Given the faster onset and shorter duration of effects, it is possible that a-PVP will be more compulsive than MDPV
via rapid onset ROA's (smoking, slamming), but it may take longer to take hold and have an easier/shorter comedown
when the test subject regains willpower. Vapers may experience throat pain, lung pain, chest heaviness and possible lung damage (temporary, most likely, but who knows). It is likely (from SWIM's research, including contact with a professional source that suggests it) that a-PVP degrades/loses potency substantially faster than MDPV, whether in solution or not, and so care in storage is more of a factor.
