Tren doesnt convert into DHT which means that finasteride is useless against it. Finasteride only inhibiits the 5a-reductase enzyme which is what converts Test into DHT. Tren doesnt go through the 5 alpha reduction in humans. I know that Finasteride is useless against Tren for this reason, but I dont understand why it causes hairloss in the first place.
