allright as you all know finasteride not only affect dht but also a lot of other (neuro)steroids
also this thread shows the link between pregnenolone and baldness

1. DHT drops 2. T increases by 20-40% 3. Dopamine increases and serotonin decreases in parts of brain 4. SHBG increases 5. E2 increases 6. FSH decreases (hence why people experience watery semen or lower sperm) 7. LH significantly decreases 8. Due to lower LH, difficulty to turn cholesterol into pregenolone 9. Increase in Cholesterol due to 5-ar action decreased in liver 10. Decrease in progesterone and its ability to convert to dihydroprogesterone 11. Increase in Cortizol / Decrease in Dehydroepiandrosterone sulfate (DHEA-s) 12. Disrupt in the production of all 5-alpha steroids (testosterone, 5a-androstan-17-diol etc)
One recent study published in Neuroendocrinology found that after 20 days of finasteride exposure, male rats showed altered levels of a whole host of neurosteroids and receptors in their brains. Thirty days after going off the drug, the changes were more pronounced than when they were on the drug.
Finasteride causes reductions in allopregnenolone, a potent, endogenous positive modulator of the GABA-A receptor, in very large doses in rodent studies.
5alpha-reductase, which finasteride inhibits, is a critical enzyme in the conversion of several steroids such as testosterone, progesterone, aldosterone and corticosterone in the brain. This enzyme converts testosterone to the most natural potent androgen DHT, and also it acts an important role in conversion of progesterone to dihhydroprogesterone (DHP). DHP is further converted to allopregnenolone (5alpha, 3alpha-tetrahydroprogesterone) by 3alpha-HSD. Allopregnanolone is a modulator of gamma amino butyric acid type A receptor (GABA-A), and increases chloride conductance. This neurosteroid has been found to exert anti-convulsant, anesthetic and anxiolytic effects. Moreover, change in the levels of allopregnanolone is found to be associated with depressive disorders.
If you must use Propecia, you can likely offset this reductions in allopregnenolone and the resultant cognitive deficits and depressive symptoms by supplementing with Pregnenolone. Pregnenolone is metabolized sequentially to 5a-dihydroprogesterone and 3a,5a-. tetrahydroprogesterone (3a,5a-THP) or allopregnenolone. Based upon this data, it would be prudent for anyone currently using Propecia, Proscar, and/or Avodart to adjunctively use 50-100 mg of Pregnenolone a day. Your mood and cognitive functioning may well depend on it.
