The lab ran this sample a second time in an attempt to differentiate it. While 3-fluoro-a-PVP and 4-fluoro-a-PVP retention times are very, very close, this sample is closer to 4-fluoro-a-PVP. We are unable to be more certain than that with ring substituted substances such as these at this time.
Send in a sample for testing
DrugsData tests all psychoactive drugs including ecstasy tablets, powders, research chemicals, novel pschoactive substances, and other drugs through our licensed laboratory. Ecstasy/Molly tablets cost $100. Recreational drug powder/crystal/blotter costs $100. Pharmaceuticals, supplements and all others cost $150 per analysis.
Should the public have access to independent analysis of the products they consume?
The vast majority of analyses of over-the-counter, prescription, and recreational drugs are performed in secret with no independent oversite or review. No other historical record, free from politically-controlled agencies, is currently available in North America nor most other parts of the world.
DrugsData, a project of Erowid Center, needs the support of professionals, students, parents, individuals with means, and small foundations for a total yearly budget of around $120,000 USD. Erowid Center's general budget and the co-pays we require fund most of this cost.
