Anciaki

If cheminsty is not an option. But I am very confused by why everyone would say it is the oxalate? mah

Hello psychonauts, could you help me understand which kind of substance I have I'm dealing with? I bought this 5meo six months ago from a reputable vendor in UE and smoked 14mg for the first time one month later: the experience was very intense so I put my stock in a cold and dark place and forgot about it. Color is very brownish/amber with some darker spots and consistence is sticky/oily. The vendor says it is the oxalate salt and from another post on reddit about that product of that vendor people say it is oxalate. BUT Few days ago I decide to try a more gentle approach by boofing it, as many suggest and as it is shown here in the video (https://www.actualized.org/insights/how-to-plug-psychedelics ) and when I went to dissolve ~7mg in the water it didn't dissolve! Even with 7ml of liquid it still didn't so I added some vinegar and magically dissolved. The experience was very soft and zero visuals but very zen. Have I done something wrong? Is it possible that I have the freebase instead?? Thank you everyone
