Color Difference

[iPeat]

This is my first time uploading a picture here so hopefully it works.

I noticed a definite color difference when switching from Health Natura brand Methylene Blue to Oxidal (Idealabs product). Below is a picture of both products diluted in 4oz of water. Health Natura on the left and Oxidal on the right.

The bottle of the Health Natura product says 1 drop is 100mcg of MB. Oxidal's bottle says 1 drop is 0.4mg of MB. I used 4 drops of HN on the left to equal the amount of MB of Oxidal on the right. There's a clear color difference.

What gives? Does anyone else have experience using both products?

This is what 1 drop of each product looks like in 4oz of water. 100mcg of HN's MB of the left. 400mcg of MB from Oxidal on the right. Subjectively, it looks like HN is 4x more concentrated than it states, or Oxidal is 4x less concentrated.

Scary to think that while I thought I was taking 400mcg of MB (4 drops of HN), I may have really been taking 1.6mg.
