Early last month, I posted about L-Carnitine's effect on preventing muscle loss and actually rebuilding muscle in dogs. Here's the thread : http://www.refugeforums.com/threads/building-muscle-and-preventing-muscle-loss.1023852/ Now after only a month or five weeks or so, I'm hearing back from folks that they are noticing significant changes. People are reporting increases in thigh circumference of 1/2" up to nearly 1"even in dogs 9 or 10 years old -- that had significant muscle loss. Some of these were dogs that had CCL (ACL) surgery and others who had muscle loss due to old age. This is the kind of feedback that makes me smile for sure. I don't have this listed on my website yet, but if you are interested, just PM me. I have 250 mg capsules of Pure and Natural L-Carnitine. 100 capsules are $28. .
