I'm wondering whether freebase or HCL form of 5-MeO-DMT is better for long term storage?
It would be stored in a vial, in the freezer.

I have some HCl & i tried a very little bit, i didn't feel much apart from an intangible goodness.

Thanks for any information

the salts are usually more stable than freebase but swim doesn't know specifically for 5 meo

I wonder this also. I've tried twice so far and am willing to keep it and do it once inna while.
I have it in HCL form and make me think this should be more long term storable.
I left it in dark airtight but room temp.

How did you try it? Sublingual, insufflated, smoked?

Not smoked. Never bothered freebasing it.
I've try SL, IN, O.
Heart race made me think of Bufo.
But when tripping it is quite wonderful world opening.
