I’ve been using DocSpartan since it’s debut on Shark Tank. It’s the only thing I’ve found that combats fever blisters taking them out in 1/4 of the time it normally took before DocSpartan. I use it on all my scrapes, scratches, cuts, burns, and blisters. I’m grateful I was able to get it in the quantity I recently purchased as it saves me tons of money. As long as it does the job it’s been doing I will continue to purchase it. Thanks for a great product.
