Testosterone base test. The best steroids test kit on the market.

If you are testing only pure powder, the color will appear as follows: Vial A will show a red-green color, and Vial B will appear yellow. Under UV light, Vial B will fluoresce blue. When testing a final product with GSO (Grain Seed Oil) as the carrier oil, you will notice a gradual color change in both vials, shifting from yellow to orange, and then to a dark yellow-greenish hue under UV light. With very high concentrations, you may observe a slight blue fluorescence. The type of oil used as a carrier does not affect whether the sample will fluoresce if a hormone is present. However, the intensity of the fluorescence may vary depending on the oil, as different oils absorb and reflect light in different ways.

Colors in both vials getting a little darker red but it is not indication of testosterone base presence we need to do UV test.
