I Have experience with lsd, psilocybin, ecstasy, mephedrone, benzo's, opiates and a few others. Found this to be the most potent stimulant I have tried, but still a worthwhile drug. I consumed 50 mg by swallowing and had effects lasting for ten hours.

The PsychonautWiki Journal logging app doesn't include every substance. To track Naphyrone there, start adding an ingestion, search for the name, and choose to add it as a custom substance. Paste these values:

Description
Naphyrone Source: SubstanceSearch (substancesearch.com) Oral dose (mg): common 20-35 ยท strong 35-50 ยท heavy 50+ Oral duration: peak 6-12h ยท total 6-12h Note: ranges are harm-reduction guidance, not a prescription. Start low, go slow, and test your substances.
Tip: for quicker logging you can also add a Custom Unit in the app, e.g. common dose ~ 27.5 mg (Oral).
The app keeps custom substances simple, so the full dose ranges live in the description text above. Ranges are harm-reduction guidance, not a prescription.
Tolerance
Build-up
develops rapidly, often within a single session; compulsive redosing common
Reset
a few days for acute tolerance
Tolerance Decay
Full tolerance
3d
Half tolerance
7d
Baseline
~21d
Acute tolerance: develops within a single session โ the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.
Tolerance data are largely anecdotal, inferred from pyrrolidinophenone stimulants; users report acute tolerance and reduced effects on consecutive days with partial recovery over 1โ3 weeks. Data quality: low/anecdotal.

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. To be honest the first try, like the majority of the time, was pretty good.
***This trip report covers 2 days The first day i had good sleep and ate healthly second day all i had was breakfast.*** I acquired some Nrg-1 yesterday despite the fact i heard all these horror stories i was willing to give it a try, Inside the bag containing 0.5 gram of Naphyrone/nrg-1 was a flakey cornstarch like su...
I am very glad to be alive, but also very lucky. In the last 24 hours I have learned a very unpleasant yet valuable lesson in the dangers of NRG1 or any legal high when used to excess. Let me start from the beginning. Thursday morning - My order of NRG1 arrives via Royal Mail Signed delivery.
