6. Tangible Results in Just Days
People are seeing impressive results quickly. Additionally, WINPRO is so confident in their product they offer a 20-chew trial at a really great value. This is a 10 day trial for any dog over 20lbs. For a dog that less than 20 lbs, this trial period lasts 20 days. Since blood proteins work biologically, you will see results faster than the traditional 6 - 8 weeks nutritional supplements promise... So, instead of getting two little pills to stick into a peanut butter snack, you actually receive a bag of tasty chews to use for more than a week.
