BioTE Hormone Pellets - Anyone here have experience?

I just had these implanted yesterday. I can already tell the estrogen delivery is better than the cream I was using. I had not heard of it until my cousin told me about it several months ago, but it has changed her life. I've struggled with hormonal issues for more than 10 years. Just having an alternative to the always inadequate pills, creams, and patches is encouraging to me. I'm thinking that since they can't find any other reason for my headaches, they may be hormonal. If so, getting the right hormone amounts in a reliably consistent manner might actually fix me.

Are there any Peas on this? Other than my cousin, I don't "know" anyone else. I've done the research myself, but I'd love to hear some personal stories other than the testimonials on the website.
