Lupron vs Eligard

My IVF DR and I decided to try Lupron after 3 chemical pregnancies. The pharmacy called me today and said they had an order for Eligard. Not knowing what that was I looked it up and it similar to Lupron. Has anyone used Eligard? Does it work as good as Lupron? I’m assuming they called in the Eligard bc it’s a cheaper than the Lupron but I will pay the difference if it means having a successful pregnancy. Please someone advise! I’ve reached out to my clinic and just waiting on them to get back to me regarding the situation. If you have used either or know anything about them I’d love to hear from you! Thank you.
