DMT appears to drive just a little bit of tolerance which is negligible due to it being quickly metabolized. Never read anything about harmalas tolerance timelines.
LSD though, that leads to a high tolerance with a long time to get to baseline, doesn`t it? It is known to have a slow clearance rate which would result in longer effects and longer tolerance. Don`t you feel a reduction of effects in the 15 days interval?
Comboing with harmalas though, that should change tolerance... I presume that SSRIs lead to long term reduced 5ht receptors, or for MAOi it would lead to an increase in reuptake or reduce 5ht receptors as well. If that is so, a combo of harmala and tryptamine should drive even higher tolerances.
Also interested in knowing if you pre or post load with supplements, seeing your background on bodybuilding. I like the preloading with multivitamin, carnitine, coq10, fish oil, resveratrol, ascorbic acid for the anti oxidant properties and postloading with carnitine, triptophan or 5-htp to avoid serotonin crashes. A similar question would be if you do any detox regimen.
