Atm they claim they get all their RCs from within EU 'bests chemical factorys'.
(last part is based on trust as they provide no actual prove)
Must say after trying MDPV and Pentedrone. That its not a class that actually tickles me.
MDPV never lived up to the expectation and Pentedrone was more like a functional dirty stimulant.
Useful but not recreative on its own.
The selection offered in NL of substituted Cathinones based upon MDPV is bizar. 8 different ones,
MD-PiHP, a-PiHP, 5-DBF-PV, a-2D-PV, HEP, MDPHP, MF-PVP and NEP.
And all the analogues that appeared affer bk-MDMA, 4-MMC, 3-MMC, 4-CMC were banned.
Which is an extensive list of worthless compounds, we had Khat, Meth-cathinone and Methylone.
The rest imo is obsolete, though i get it that people loved Mephedrone, but when looking at how it spread like a plague. And when you read the reports its seems super, but so fiending and to easy to go overboard. And a bit cardiotoxic at high doses. So I never took the risk to try it. Only 4-MEC, 4-FA and 3-MMC.
First one never got popular, but the latter 2 were DOC of choice for the youth for awhile, Low standards?
