@laughlin1947 - Good morning. I do not know the names of the bio-identical drugs used. Maybe I should? My pellets are compounded especially for me with dosage driven by my specific hormone levels at the time. I'd suggest you search for "compounded drugs" on the net and learn about this part of pharmacology that is generally not understood by the general public. I first started using a compounded drug to treat ED as directed by my Mayo docs. I trusted them not to steer me wrong.

I have read many concerning articles about the side effects of HRT.

You are actually discussing what can be two different issues: (1) ED and (2) Low libido. For me, management includes two different strategies. Hip-inserted bio-identical pellets for low-T and syringe-injected tri-mix to manage ED. Both treatments are necessary.

Does that help?
