Gonal-F or Follitism

Am
Hi has anyone used either injectables? What was your follie reactions and your experience on it? Is there a difference between the two, which is better? My dr might be switching to injectables with my 5th <a href="https://glowing.com/glow-fertility-program">IUI</a>. I only get one follie on femara and she's trying to get at least 2-3 so hoping injectables will do the trick
