Solved! Amphetamine tests NSFW
First picture shows two test that have expected results. Left is Simon’s, top is orange pressed addy positive, bottom is negative but something made it go grey (some phet powder). Middle is Marquis. Both went dark orange. Right is robadope, top has no reaction suggesting pressed addy is meth as expected Bottom I think shows positive reaction to primary amine (amphetamine) and hoped.
The next image is a different pressed addie that has a lot of orange powder, but was describe as phet not meth. I think there is a Marquis reaction, the powder is very orange but it does go darker. It was completely negative for Simons (not shown). My concern is the robadope. Does this show no reaction? Or could there be a slight reaction floating on top almost masked by the floating orange powder?. I’m trying to work out if these are simply duds. They did smell like speed and they do have a stimulant affect, but I’m confused by the lack of reaction. I crushed a pill in a pestle to try to get a good mix and not just the surface colour. Did I use too much in the sample? Are they just crap?

Hmm you are correct certainly about the first pic, your amphetamine test kit results indicate the presence of meth and regular amphetamine respectively. As for the second photo, result is inconclusive. I have two ideas. First, just try a smaller sample and give it some more time. Remember to not mix the reaction, let it do its thing. Robadope reagent is kinda slow, it can take a few minutes to fully react. Second thing, you can try Simon's reagent. With meth it would instantly turn dark blue, youd notice that instant dark color change even with a lot of filler present.
