I've only used 1 research chem lab, & wut they sent me was real, it work exactly how it was supposed 2. Other than that, I usually get all my AI's & such from my gear source. As far as I kno, u need a script 4 Nolva & / or Clomid in the U.S. Those sites that say "legal" r usually just referring 2 the countries that don't regulate AAS & research chems, they will still sell 2 u in the U.S., & they will do so without a script, but it doesn't mean it "legal".
