I received my free sample of defense soap a couple of weeks ago and thought I'd share my experience.
First, a little background information. Over the past 5 months, I've had staph (non MRSA) twice and ringworm three times. It was the first time in about 7 years on and off the mat that I'd ever gotten ringworm, and after I got it the first time, I'd almost get rid of it and then have it show up somewhere else. For instance, I was washing my pillow case every day (the ringworm was on my neck), and I went on vacation (left the country) and didn't wash my pillow case that day. While I was gone, I got rid of the ringworm using lotrimin, and when I came back home late one night, I went to bed and woke up with a new case of ringworm on my face. Awesome.
When I first started using the sample of Defense soap, I noticed that my most recent ringworm went away much faster than previous cases. After it went away, I went back to the gym, which is still a ringworm cesspool. Apparently everyone's gotten ringworm while I was gone, and there are signs posted everywhere about how to treat ringworm and to stay off the mats, etc. I'm back to rolling 2-3 times a week, and so far I've had no new problems with ringworm, even though people are still rolling at the gym with the dirty worm.
As mentioned before, the soap does lather up like crazy. The one ounce sample I was given is still in my shower (although it's so thin it's almost see-through), which I think is pretty good.
I'm pretty seriously considering ordering the soap now. It is expensive, but it seems to last for a good amount of time. I think the most telling part of the soap's effectiveness is that I haven't yet gotten ringworm again while everyone else at my gym just keeps passing the crap around. That's pretty impressive. I still have the body wash sample, which I'm going to use next. If I get ringworm (or anything else) again while using the soap, I'll be sure to update this post.
