I have noticed that hCG down south is harder to get now. Several of the sources I know can't get Profasi or gonadotropyl. I don't know what is going on. As far as taking the vet version by Loeffler, I don't know if animal hCG contains the same peptide sequence as human. Or if it is different, does it matter? Just like insulin when you compare beef and pork to human, they differ in peptide sequence (slightly), but still function the same in the human body. One thing to note is that since it is of animal origin, there is an increased possibility of antiginecity and hypersensitivity reactions. So, has anybody tried Loefflers hCG?
