You took 25I advertised as LSD?
When you plan on doing that geltab, just try dissolving a bit of it in some alcohol then use Ehrlich's reagent (you can buy it as easy LSD reagent test) to identify if it is a tryptamine based chemical. At least that excludes NBOMes in almost all cases...
I'm not really interpreting as 'should i take this', we can advise perfectly well without directly addressing that with a yes or no, even if the question was implied.
Also, you could just take a little less if they are really that potent. Yes it can be scary to jump into a heavy trip, but I don't find LSD so unforgiving. Just have a good mindset and setting, if not work on that.
