The easiest way is to find a Doctor that will prescribe it.
My Doc wrote the script, and sent it to a compounding pharmacy.
I have capsules that are made for my weight .
They also have vitamins D3, and C in capsules.
One would think that this would be the easiest and best way. I am happy that you live in a place where this is possible. Unfortunately, in the blue state we live in few if any Doctors will prescribe ivermectin. Hospitals will also not treat Covid with ivermectin. This is because doctors here have lost their medical licenses for doing so and pharmacists have faced disciplinary action as well. So many people who would normally never consider taking what I consider a radical action to regain their health are doing it now with many reporting success.

I have the same from Amazon — 6 tubes — but also have 30mg pills from an online medical supply Dr., through a neighbor.
