This is a really interesting read about how the street cartridge brand TKO extracts getting caught trying to share fake lab test results on their Instagram page. The lab commented back on Instagram that the results were not authentic. Screenshot of the lab Belcosta and their comment in the link above. This is why it's vital to not buy these cheap street brand cartridges. They are most of the time low quality trimming distillate that may have pesticides or use a cheap vape cartridge with heavy metals.
