Hi all. My little girl was just diagnosed last week with diabetes. The vet prescribed Lantus, twice a day. I found a seller on craigslist who is selling a box of 5 pens for $75 (it was for him, but he was able to reduce his insulin due to dietary modulation). To be honest, I'm worried about getting drugs off of craigslist...even though the guy is a self-professed animal lover and expressed sympathy about my cat having diabetes, I'm still wary. Any advice/thoughts?
