In general, I really like the idea of crowd-funding the testing of things like HCG, and I would add in some of the other commonly used products like cialis and ivermectin.
Also, I think there is a moral and practical reason to direct purchases to non-mainstream pharma sources whenever possible since in many cases they maintained supply of key products such as HCQ and Ivermectin throughout most of the pandemic when they were actively suppressed by mainstream sources. Supporting them and Janoshik is a step toward creating a privatized version of the FDA which does what the FDA should be doing, which as I've said before seems like an inevitable necessity.
I don't trust any testing that a known independent party didn't have control of from beginning to end.
