Slower Beard Growth

I am on Testim gel for HRT. I was using 5grams per day with not much success. About 3 weeks ago I upped it to 10grams per day at the doctors suggestion. For about a week now I have noticed that my beard is not coming in as fast and my facial skin and beard feels softer.

My endo had asked about my beard growth before I switched to the 10gram protocal but did not tell me why.

Could this be an indicator of estrogen conversion and the need for a blocker?
