My extreme gratitude to Loveall, The Traveler, et al. for pioneering this method!

I have quite a bit of experience with psilocybin, but I'd never tried DMT before and was curious about folks enthusiasm. I was able to get my hands on some quite pure DMT FB recently through a friend, but I have rather sensitive lungs and so smoking it straight wasn't an option for me. I followed the steps outlined in Loveall's
summary post but still had an incredibly bad time (covering my mouth and nose to stop coughing, only to burp up vapor lol

) Picked up some pH strips and turns out I was still around 8.5-9, added more citrate until I was just on the acidic side of neutral. My ratio ended up being closer to 1g + 0.55g + 2g. Gentlemen this shit is like candy, many thanks.
Pro tip for the newbies - remember to finely grind up your citric acid or you will be waiting forever for it to disolve!
The only issue I have with it is that after a while the PG irritates my lungs and has me coughing up slime. In the long run there's no way this is sustainable health-wise, and so I wanted to ask whether you had ever considered another carrier solvent? My friend actually uses DMSO for this, 0.7g FB into 0.3ml of solvent. Has anyone here looked into this before? He just makes FB carts, but DMSO has high solubility for citrate too so I assume you could still salt it just fine for shelf stability. (He says that folks haven't complained about harshness with the FB+DMSO, so maybe the solvent itself is doing something to neutralize? That or folks are just used to FB in a way that I can't handle.) It should also majorly help with absorption because DMSO is known to carry solutes through the skin, which should give you better yield per hit. I need to save up some cash before I can try this out myself, all of my FB went into my batch of PG citrate juice, but I wanted to throw it out to the community.
The biggest issue I can see is that you could get breakdown of rubber gaskets/glue holding the assembly together. I've been using iKrusher all-ceramic 'Karno' carts along with their S1 variable voltage pen battery that I got from VPM, and I've currently got a cart sitting filled with just solvent to see if I get any breakdown. According to my friend, I would want to run on the lowest voltage my battery does, 2.7V, and that "Not all carts work well with DMSO, some might leak or burn it. If it smells like a rotting carcass it is burnt and toxic, but a garlic smell is okay." Smelling pure DMSO I find that it has kind of a salty/seafoam/garlicy/off milk sort of thing going on, I imagine it could taste alright alongside that unique spice-y goodness?
A quick google search says glass and BPA-free plastic are the best for storage of DMSO.
Sigma-Aldrich's product info sheet for DMSO says more specifically that it is compatible with many common plastics, but there are a few to definitely avoid.
Thanks again! Made my account to post this, and I look forward to future explorations with you all. Let me know what you think!
