Higher Scalp T Levels with Avodart?

Dr Rassman
Have you heard any speculation concerning the significantly higher scalp T levels with Avodart vs Propecia and long term hair implications?

Thank you

Testosterone increased 4.4% for Finasteride, 6.4% for 0.05mg Dutasteride, 16% for 0.1mg Dutasteride, and 27% for 0.5mg and 2.5mg Dutasteride. Although the rise in Testosterone may seem high, the Testosterone levels were almost always within normal range according to Roger S. Rittmaster, MD.

Scalp DHT measurements were also assessed for both DHT and Testosterone. Scalp DHT was decreased 27% for 0.05mg Dutasteride, similarly for Finasteride (38%) and Dutasteride 0.1mg (37%), 54% for 0.5mg, and 82% for 2.5mg Dutasteride. Rittmaster concluded that these results show that most of the DHT in the scalp comes from type 1 5-alpha reductase.

Scalp Testosterone rose 24% for Finasteride, 46% for 0.05mg Dutasteride, 44% for 0.1mg Dutasteride, 104% for 0.5mg Dutasteride, and 154% for 2.5mg Dutasteride.
