I did contact AR-R. Sent a few emails back and forth, and apparently they have had no issues with that batch.
I actually have two bottles from the same batch. It's pretty obvious when an A.I. is bunk when you change bottles, using the same product, and it stops working.
In the end, I am left with crap and am sore about it. If AR-R cared, they would try to fix the situation for a customer who has spent 1.5k on research chems in 6 months.
If AR-R's business practices have changed, other people need to know.
