Not sure about the cost of the flush...check with Gizmom on that. I pay $60 for implanting embryos plus mileage. Add Lutalyse, CIDRs, Cystorelin, Estrotect patches etc. to that. You also want to inject with MultiMin as well. Your recips need to be in good body condition and gaining weight. The higher the body condition score the better. This has not been a great summer to implant embryos in Florida because of the miserable heat. Maybe it's better where you are.
