Oh, OK I got what you're saying (you need to edit your post). Yes, its 4-po-NMT thats baeocystin. But, I'm wagering 4-ho-NMT will have VERY similar subjective effects (at least with interference with the respiratory system). Possibly even more acute.
I don't think it will be a problem or maybe even that noticeable unless you are a 7-year old, elderly, or have some sort of problem breathing.
And I agree with you, its highly likely that 4-HO-NMT is in mushrooms too, just not yet isolated (4-PO-nmt is in such small amounts anyways).
Regardless its exciting to get access to 4-ho-nmt! Exciting times! Now just give me 4-ho-5-meo-dmt and I'll be straight for awhile.
