Very pleased with the products. Thank you.

Regarding the product, I am well-pleased, expecting excellent purity and standardisation in them for best effectivity. Thank you!

p.s. When the charge came up on my cc statement, I did not recognise it as from Compass Labs, since it is under another name (Compass Solutions LLC). When searched, this company shows up as offering business internet projects. I had my card cancelled, thinking it had been compromised. Later, while clearing old emails, I came across the purchase confirmation and saw an email address @compasssolutions.com at the bottom of the email. :(

Great Product!

The research and applications of DMSO is really fascinating. This is a great product.

Quality sells itself

I bought this product because my wife has been having lower back pain issues for some time now. I've known about DMSO for a while but for some reason was slow to take action, that was my bad. I read a recent article...or was it a video clip I watched....? Anyway, it was like a light bulb went on in my head and I decided to buy it.

Considering my wife's back pain has been pretty bad, after 2 days she swears that she felt markedly different. Today is the third day and she now swears that there is no doubt that she feels different. She used to have difficulty finding a good position to sleep or even sit in but has no issue now. I have to admit, even I'm stunned by the speed at which the change has taken place.

I apply it on her back twice a day and she feels so much better she's taken to finding out more about DMSO for herself. THAT is how profound the impact is for her. I'm using a 70% concentration on her (I'm also using it too) and there is no complaint as yet concerning skin irritation other than a slight stinging sensation.

Truthfully speaking, it does have an odor. I don't think it's possible for DMSO to not have an odor. But here's the thing, for what it does for the human body, I'll take the odor any day for the myriad of benefits it affords...bottom line!

I chose Compass Laboratories because of my confidence in their quality. I based this decision on their Methylene Blue product which I have been using for some time and reaping the benefits of as well. I strongly recommend Compass Laboratory products. Did I mention the DMSO comes in a glass amber bottle? Yah, no compromise!

Great product and excellent customer service

I highly recommend this company for their high quality and wonderful customer service. I called the number I found on their website to ask a few things about their DMSO products. I was pleasantly surprised that a very personable and friendly chemist called me back (on a holiday) to personally answer my questions. The chemist even left a personal cell number and answered my return call after hours (we live in different time zones) during a family event. That is above and beyond phenomenal customer service. This company obviously cares a lot about their customers, their products and has very high standards. It makes me trust that they stand by everything they do. Two thumbs up, way up! Thank you!
