If you do not have too many samples to test the mini test kit is for you. But if you are testing more the professional test kit is the best choice. It is very simple to use the test. You drop your sample into test vials, liquid, powder or pill (grinded into powder). You watch the color change under day light compare to the color chart or samples. Then you take 365 nm UV light point at the test vial and see if there is fluorescence. If you get the right color (fluorescence) then it is pass, it contains the right substance. No fluorescence means fake product, no hormone inside. Vials A and B will produce different colors to different steroids, this how you can distinguish which one you have. You get detailed instruction with the test kit. UV light is sold separately, you can choose option with or without UV light.

You can also include handy 6 position vial rack; it is very useful tool to protect the vials from spilling test reagent. The test reagent is corrosive, accidently dropping and breaking the vial might leave permanent stain.
