FYI, from the interwebs:
After the positive fentanyl strip results that were tied to liquid 5-Amino-1MQ sold by the vendor Beebo, Vanguard Laboratory has now run more testing. Dustin from Vanguard tested 10 separate 5-Amino-1MQ samples from different suppliers, covering vials, capsules and an authenticated Sigma-Aldrich reference standard.
At high concentration, every sample, the reference standard included, gave a presumptive positive on the fentanyl strips. When the samples were diluted per the strip manufacturer’s instructions, though, all of them came back negative.
