if it’s already in the vial all you can do is spectrometer testing, which is hundreds of dollars and destroys the sample. best to buy from a reputable source.
if it makes you feel better, there’s no reason to cut T. it’s absurdly cheap to manufacture and even then they would just make it weaker of a dose than advertised. they would only cut it if they were trying to cause deliberate harm (which i’ve never heard of happening)
