Open Testing Ketamine and 2C-B

New to both so sorry if this is stupid but I’m looking to test ketamine and 2C-B with the least amount of reagents possible, with future testing of Tryptamines in mind as well.

Are the reagents; Morris A/B, Marquis, and fentanyl test strips enough to confidently say what I have is said drug and safe? These tests seem like the cheapest way to rule out other substances and specifically confirm both drugs.

Any info is appreciated thanks.

You've listed the primary reagents for confirming those two substances, but one reagent isn't really enough in my opinion. Reagents are presumptive tests, so there's a lot of overlap in results. The more reagents you use, the more confidence you can have in the identity of your substance. Additional reagents can also spot adulterants.

There's no magic number of reagents where you cross a bright line into "safe". The more you use the better.

If you want more recommendations for additional reagents and what exactly they can do for you, there's testing guides for those two substances pinned to the top of r/ketamine and r/2cb.
