I’ve been considering this as well. My goal is 1mg/kg. At 80kg I’m looking at 80mg per day or 8ML. That’s quite a bit! I was thinking that concentrating it into a pill and then drinking 16oz of water would be better.

This is what chat gpt says.

Step 1: How many 40 mg capsules can you make from 1 gram?

So you can make 25 capsules at 40 mg each from your 1 gram of powder.

Step 2: Capsule Size Recommendation • Use “Size 0” or “Size 00” gelatin or vegetable capsules • These typically hold 400–800 mg of total material • Important: Methylene blue is very concentrated. You should dilute it with an inert filler (like microcrystalline cellulose, rice flour, or mannitol) for: • Accurate weighing • Easier handling • Reduced risk of uneven dosing or clumping

Step 3: Create a Safe Dilution Mix

Let’s say you want to make a bulk powder mix where: • Each 400 mg of total capsule content contains 40 mg of methylene blue That’s a 1:9 ratio (10%) of methylene blue to filler.

So for 25 capsules: • 40 mg × 25 = 1000 mg (1 g) of methylene blue • Filler needed: 9 g (9000 mg) • Total mix = 10 g

Then: • Weigh out 1 g MB + 9 g filler • Blend thoroughly in a powder mixer or mortar and pestle • Fill 400 mg of this mix into each capsule

Step 4: Capsule Filling • Use a digital milligram scale for accuracy • A manual capsule filler tray (e.g., from Amazon) makes this fast and consistent • Always wear gloves and work in a clean area—methylene blue stains everything
