Ive been using Ovidac for a few weeks now and seems to work just fine. Balls are increasing in circumference. Pinky measured them for me with his micrometer.
Have used Pregnyl, Ovidac, Beifang, PPC, livron, and chorulon from the vet..
Honestly they all worked fine and the only difference was the vet stuff if you use the water provided it burns.. just had to use bac water and it solved the issue.
Its like any anything we use, if its properly dosed and real the packaging/name makes zero difference its all the same thing its HCG.
