That sounds like a really confusing experience. I would be a little bit dumbfounded myself. You hear verified and un-verified stories about hard drugs like Fentanyl being cut with stimulants like Methamphetamine or even Benzodiazepines. It is a mystery why someone would use Cocaine to try to fool someone regarding their Methamphetamine purchase. It seems to me that just for purely economical reasons that this makes no sense. The problem here is, we really have no way of getting you any kind of answer that you can actually take to the bank regarding what your drugs might actually be.
Not everybody is willing and/or able to have their drugs tested by a legitimate laboratory. It depends a lot upon regional availability, although mail-in services do exist, for practical reasons, most drug users are not at all willing to mail drugs, wait for an answer and then use. It just doesn't really work that way and we all know it. The truth is that you have probably gotten a pretty good answer for yourself just by taking your drug test. The exact contents, ratios etc. of your drugs will probably remain a mystery, as will the motivations of the person you bought them from. You do have somewhat of an answer though through your drug test that you can use as a point of perspective.
