I know right?! Feeling pretty discouraged about this whole situation since I'd bought what I thought were third-party-tested batches, but now there's confusion around what those extra letters on the label actually mean, someone claimed it was just referencing which warehouse shipped them, which had me relieved for a second, but now I'm second-guessing whether it's genuinely the same product, honestly no telling at this point. Got roughly six months of Tirz stocked before I'd even need to touch what I just bought, so hoping there's some clarity by then. Trying to put together a small group interested in splitting lab testing costs, four people would run about a hundred dollars each using a domestic lab. Not the worst deal.
