When I got the kit for the first time I did not have clue what to do, it took some practice and experience.
This is common misunderstanding about labmax, they say in the instruction that it is not for purity testing but it can do more than you think.
look at the material, the higher deca concentration then in goes from light green to darker green under UV.
low test enan will show as yellow but higher as blue.
and there are more tricks with other steroids too.
it can give you pretty good idea how potent the sample is but it took me a year of testing to figure it out.
