These are some recent finding from my clinic. PetMeds buys all products second hand. Some stolen by employees and sold to petmeds. They send faxes to clinics asking doctors to buy products and sell to them. Then, the manufacturers do NOT give you any supportive care if you need it. IE -- adverse reactions. THEN, the most recent finding is that we have had three separate clients contact the manufacturer/pharm company about the lot number. They have been non-existent. Meaning PetMeds is making up lot numbers... which to me says RED FLAG all over it.
I don't trust the companies. I don't think it's worth it to get the product for that cheap and not know where it came from, how it was stored, and that it could even be artificial.
The best option is to find a veterinary clinic willing to price match the company. That way you can get quality product, for decent prices.
