I might have this absolutely wrong but : Test4PayUSA | Torhoo darknet markets
Now if Test4Pay is looking for someone to test a product then report back with quality and results of legitimacy then I am a very very very experienced user daily user and for 16+years with 2 breaks in between that last maybe 2 months each. So depending on if it's an opioid or amphetamine I can determine whether it's S-F tier quality and whether or not buyers should be aware that extreme caution is necessary when using.
Now the more I research and see what people are saying, I am getting the idea that Test4Pay means using a test kit to identify what said product is cut with and to avoid the vendors whos products are testing positive with Fent.
If it's not the prior then I apologize for my post. But just in case it is my original thought then I am a willing participant and the tolerance I have to Fet (not in the pressed M30s form I mean the straight off the stamped brick fet) is astronomical. So not only would I be able to tell what's strong strong dangerous strong or what's bunk AF, I would be able to find someone who can provide the kind of quality that I so desperately wish people would bring back from like 3-4 years ago. Lol sorry anyways please let me know
I'd be honored.
