Masteron propionate test. The best steroids test kit on the market.

Before you start the test, you will need a 365 nm UV light source. For example, you cannot use 395 nm light, as it is not UV light—it's like using red light instead of green light. LabMax has specifically designed and manufactured 365 nm UV lights to ensure compatibility with this test. Many of the so-called black lights sold on Amazon and other platforms are actually 395 nm lights.

You should add a small amount of the sample—typically less than the volume of the test reagent. This usually amounts to one or a few drops of oil from the syringe. When adding oil, you will notice a slight initial color change, with the oil gradually becoming darker red. However, if you add raw powder, there is no immediate color change, and it may take longer for any reaction to occur.

For oil-based samples, it takes a few minutes for the fluorescence to become more apparent in vial B under 365 nm UV light. The fluorescence will appear yellow to dark yellow, while the sample in vial A will look light brown to violet. In contrast, a sample containing raw powder will produce blue fluorescence in vial B and brighter blue fluorescence in vial A.

If no fluorescence is observed, it indicates that there is no hormone present in the sample. If the fluorescence appears in different colors, it suggests that the sample may contain something else or has been contaminated with other steroids.

The type of oil used as a carrier does not affect whether the sample will produce fluorescence if a hormone is present. However, the intensity of fluorescence may vary depending on the oil because different oils absorb and reflect light in different ways.
