Looks great!
If you want the full alkaloid just consume as is. Depending on the potency of you starting material the resin probably contains between 500 mg - 1500 mg mescaline if all the mesc was extracted by the boils.
If you're looking at a full trip experience and you have psychedelic experience you probably want 400-500 mg at least.
If the resin is taken you could split it, eat half of it and if you're not satisfied by the results after 2.5 hours take the rest. As the total experience will intensify after second dose +2 hours you probably still get the full experience for 4-5 hours.
Enjoy the experience. Mescaline is such a valuable substance.
Btw what is a bubble bag? I'm interested to make that kind of crystal resin, convert that to Hcl, wash with IPA and acetone and your result looks perfect for that. If the natural salt form is weaker than Hcl this should work.
It could mean that a solvent free pure mescaline extraction is quite easy to do with some boiling, HCl, IPA and acetone. No need for nasty solvents or expensive d-limonene anymore.
<EDIT> I just googled bubble bags and see what they are know. Thanks for sharing I'm gonna try this out soon.
