Cut making me dizzy? Or redose?

Im not a new user by any means thats why it keeps puzzling me.

For reference, I dose 2-300mg ata time sometimes I slam sometimes I smoke and the odd time I put it in my nose. I redose with smoking every few hours maybe a few times tops and if I bang it I only do it once in a day.

I also keep up on sleep, food and hydration. This “new” junk or p2p or w.e its called is definitely weaker by a long shot than Im used to getting but, is it cut with something im not used to? Has msm and n-iso always been a thing?
