My rat is taking 50mg/ed oral winny capsules. The capsules are from a UG lab. Their is some choc protien powder also in the capsule to fill it, I was doubtful so I contacted my source and questioned this. He guaranteed a refund if after 2 weeks my rat does not like the product. Are 2 weeks long enough to see if the product is legit. What should my rat see or feel within 2 weeks to know they are real winny? is it sommon to have the capsule filled with protien as a filler since the winny itself cannnot fill the large capsule?
