in my own experience, as soon as you challenge a sponsor you are immediately labelled as lying or scamming. It sucks because while that certainly happens, the burden should be on the truth, not on how popular or well known or how many good orders they did in the past.
Not sure what this phrase even means. The burden is on the tester. Or the purchaser. These colorimetric tests are horribly inaccurate. They work occasionally but rely on specific chemical bonds and reactions to those various bonds. Even small mistakes can lead to false or inconclusive results. None of these are even marketed to law enforcement or customs. These tests are marketed to the public.
Furthermore, colorimetric tests are going to have problems between similar molecules. The only difference in color in those tests between nearly identical compounds would be from other elements in the solution, oil, BA, BB, etc. And tabs have similar fillers and possibly reactive elements.
I don't trust these labmax home tests. I do know they have consistently tested excellent and even many other sellers use their raws. Many. Making this thread was the exact opposite of following the proper procedure. You should have contacted a staff member first who could have discussed this with the sponsor, and we have resources for mass spectrometry and HPLC tests on anasci by real labs.
Maybe every sponsor should drop a few hundred for testing everything you think might be off and your little Hasbro $20 test kit "proves" your suspicion.
This was handled poorly, amateurish, naively, and just plain bad. But hey, let it rip. If no staff is going to say anything about it, neither am I. I still use them and have 100% confidence in their quality. I'm successfully using some of their products right now and perfectly satisfied.
