## 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.

### ⭐⭐⭐⭐⭐ Effective!

### ⭐⭐⭐⭐⭐ Great product

This stuff is awesome well worth the money

### ⭐⭐⭐⭐⭐ Where'd my ADHD go?
*by A***W on June 11, 2025*

I'm an avid supplement user. Rarely do i find a product that changes my life. After nearly 2 years on this stuff (about 30mg a day) I feel like a different person. I never knew what a normal brain felt like until now. I'm not saying this has cured my ADHD, but dang, it sure has come close. I think better, feel better, have less anxiety and even have normal social interactions. Just seeing the change in me has encouraged like a dozen friends to get on this stuff. I'm watching in real time as others experience the same benefits. I have tried other brands, I keep coming back to this. Highly recommend.
