I'm starting HRT and none of it is covered by my insurance. I have two options afforded me at this time. Tev-Tropin or Omnitrope. Both with a prescription. I researched them both and they both appear to be the same just different names and different sizes. Omni 5.8 mg and Tev 5 mg. Both have 191 amino acids and same molecular weight. And both are synthesized in a strain of Escherichia coli. Both indicate same side effects and precautions. Can anyone tell me if there is a difference other than price?
