Third-party testing is when a manufacturing company sends its product to an outside, unbiased lab for testing to see if it meets the standards of the company, and to ensure that what is on the label is actually inside the product. Now, that is fine in the legal market where the manufacturer obtains legal quality certificates according to their results, these certifications are constantly monitored by the companies that grant such accreditations and even so, they cheat with that, what can we expect in an illegal market… where there is no such certificate, this is done only for marketing by the dealers so it would not be smart to trust in the results test of samples sent for by the source itself, he could send real samples for the test and then sell cheap garbage instead (another way to scam). In the end, you have to make a test by yourself if you want to be sure…
