Pregnyl vs Ovitrelle

I will start adding HCG to my protocol in hopes of battling my ongoing sleep problem on TRT.

Pregnyl is out of stock in the entire country so my only option is Ovitrelle.

From what i read Ovitrelle is engineered form of HCG. Please forgive my ignorace but does that make any difference at all vs using Pregnyl ; in terms of it’s effects , it’s dose and protocol etc.?

Anyone have experience with it? Anything i should be aware of? Can i inject it with T in the same syringe? What dose is a good starting point?

Thank you.
