COMPASS LABORATORYMethylene Blue 1% | USP Grade | Large Refill Bottle | 1 drop contains 0.5 mg Methylene Blue | 250 mL Glass Bottle

Q: how many drops in a mL?

10 drops = 5 Mg, 2 x day is the usual dose. The literature works in Mg rather than Ml.

Q: There is no contact number for compass lab, although they state that a certificate of analysis is available on request. why not just publish it here?

You can simply send a message through Amazon but the certificate is also available in the pictures section.

Q: 237 ml is 8 oz. size in discription is 50 ml. is it one 237 ml bottle or five 50ml bottles?

It is one 237ml bottle. I ordered the 50ml bottle initially but realized I would need the larger bottle if I wanted to take Methylene Blue in the larger doses I need. I'm taking 20 drops twice a day at present so am going through the 50ml bottle in 3 - 4 weeks. Loving the results so far. Greatly helps my short term memory issues.
