So, what's some kind of topical dose that would actually be considered effective? Don't tell me %, that doesn't mean anything (without considering how many mL you are applying). 500-600 mg spread across the scalp? Would that be comparable to 2 grams oral? Can we even dissolve that much in the usual vehicle?
If I'm doing a group buy, I want to have enough substance for at least 6 months (a year would be even better). At the current prices, nobody will be buying more than 200 grams of Setipiprant. That is only enough for 100 days orally. Given how much of a hassle group buys are and all the potential issues (payment, supplier, customs) it can take up to 2-3 months before you finally have the stuff in your hands, and that's when the number of participants is moderate (10-15). If there is a lot of interest it will probably take even longer. What are we all going to do after a mere 3 months when that Seti runs out? Never mind I can't even afford 200 grams, that is crazy money. I could take 50-60 grams at Lyphar prices.
The oral version is in my opinion, plain and simple unaffordable at this stage. So my vote would definitely be for the topical salt. If JLF supplier prices are real, and if the supplier is good, I would take 100 grams at that price. That would be enough for 200 days of topical use @ 500 mg/d. If it would work, it would be a pretty good deal.
