    Pretty Much Zero Fun positive exp #92198

    Helluva Drug I'm 21, male, pretty basic experience with psychedelics. LSD, mushrooms, weed, opiates, a couple 2c's, DMT, MDMA. MDPV does not belong in the same category as the aforementioned substances. It is one hell of a drug, but it is by NO means recreational.

    MDPV Amazing I have purchased pure MDPV multiple times and can say it is not my favorite drug but the price and high is great. Everyone seems to hate on MDPV. I have gone through grams I came down. I have vaporized insufflated and orally.

    One Hell of a Drug positive exp #86062

    I had the most amazing experience on this drug. In retrospect, I would do this over and over again. I can see why it is said to be highly addictive, feeling the need to redose constantly as my friends all tried more and more of the chemical.

    I sought to purchase either Prolintane HCl or MDPV to experience an uncommon stimulant with my friend Drew. MethyleneDioxyPyroValerone won. Got lucky with Prolintane HCl just once, which I predict to be the next wonder designer drug that catches on as its legal worldwide and OTC in Spain.

    Very rarely do I ever feel compelled to share my experiences with masses of people, but this is one that I feel very good about. Methylenedioxypyrovalerone is pretty much unheard of in most drug cultures. I guess one could say it is the 'new kid on the block', though pyrovalerone has been on the market since the 60's.

    My experiments to date with MDPV have left me feeling rather unimpressed. Itย’s adequate for use as a stimulant and while I enjoy the primary effects of the substance, the harsh come-down usually renders the entire experience not worth the ultimate punishment.

    Approximately four years ago I saw a short documentary on VICE about a young man traveling to Nepal to partake on the perilous journey to consume Mad Honey in the Himalayas. Like many, I was attracted to how the honey was portrayed, touting it as a psychedelic.

    Hi All I thought I'd better post this to a forum while I'm in the right frame of mind to, as I'd like to give you all a heads up on a few of the 'issues' I have encountered with NRG-1, since my first try in early April.

    Hello, I have used tiny amounts of MDPV on a few occasions. I do not at the moment have 0.001g scales although they are on their way and should be with me soon. Although I do not have any scales that can measure out 10mg accurately, I felt that I could eyeball the dose on the first few occasions.
