Any difference between fertility drugs from us, eu or other?

May be the same, but: I don't advise getting fertility drugs from outside the us as they may be improperly stored, expired or even counterfeit. Pills may be stable in storage but could be labeled in another language . Injectables like follistim, Gonal-F have equivalents in other countries but these meds need refrigeration. No way to tell if they are exposed to heat unless your treatment doesn't work, not worth the risk.

The same: Medications sold in th us or other countries may have different trade names. Drug companies give medications different names in different parts of the world. As long as the generic name and dose are the same, these medications should have the same effect.
