Hello everyone. I'm going to keep this short if I can.
I have a yellowish lustering powder that I got from freebasing a very watered down Iso. solution that contained my previous Chali pulls (all mixed together as I don't usually have time to evap large amounts of solvent: also had a small amount of YOPO pulls added) that I tried last night by a few methods:

Vaporizing (Light bulb vape): Very hard to vape from what I have noticed, unless I am doing it wrong. powder turns from yellow color to white then to black and does not liquefy.

Intra-nasal (or however you spell it): Effects were not noticed until 5 mins after wards, and were mild compared to the amount of material taken up the nostril.

Sublingual: This one seemed to work the best (either that or it all kicked in after I did it this way). .25g Under tongue, tastes like salt and baking soda with a few other unrecognizable tastes, solution (with saliva) was spit out after about 3-5 mins as I felt it after 2.

Effects Summery:
Mostly tactile and bodily sensations. Very strong feeling of mental alertness and thoughts were very trippy (hard to explain but I was indeed tripping mentally). Visuals were mild, but I feel their was a presence of Bufotenin due to my previous experiences with YOPO and how both of these substances produced a change in color vividness and deepness (obviously YOPO being stronger).
Things would get colorful outlines and were moving/reshaping themselves. Static on surfaces. very very mild CEVs. Mass feelings of empathy and euphoria. STRONG couch lock effect, but I could still move around (stumble around) at this dose.

Now before I get anything about how 5-meo and Bufotenin are EXTREMELY DANGEROUS at unknown doses and large doses, note that I did in fact know that my powder was contaminated by baking soda due to how it burned, tasted, and looked (although some of the luster of the powder could indeed be small xtals). I had quite a bit of baking soda precipitate out of saturated solution when I was freebasing.

Feel free to ask questions, My main question is: Is this mostly 5-meo? I have never experienced pure 5-meo so I cannot judge accurately but from what the effects seem like compared to that of other experiences I have read it seems so.
