Finasteride W/ Deca or Tren, a no no?

Can someone knowledgeable on the subject please explain why using finasteride w/ deca or tren will only worsen the hairloss in MPB prone individuals? K for help, peace.

Here is the problem as explained to me by Stew Meat...

You have 5-alpha reductase that converts some substances like testosterone into DHT. DHT is much stronger androgenically. Finasteride does not block but rather prevents the conversion.

Deca converts to DHN via the 5-alpha reductase. DHN is weaker then the base product (DECA). If you use, finasteride while using DECA, then this conversion is not done. This would cause a more potent compound to be present which is more likely to cause hair lose than DHN.

(Again this was from Stew Meat)

Awsome reply TxLonghorn, just what I was thinking, but just wanted to be sure. So that would mean that gear like tren is easier on the hairline (Ive heard that even though tren is a DHT deriviative, it isn't that strong on the AR as other compunds like Test or Winny), so one using hairloss topicals to protect the scalp should be a great preventive measure. K for you bro.
