## Questions & Answers

**Q: Does this contain mercury?**
A: No, not at all.

**Q: how many drops in a mL?**
A: 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?**
A: 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?**
A: 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.
