But at the same time, if finasteride inhibits roughly 70% of DHT, and DHT levels are higher at night, then 70% of your night levels of DHT are still higher than 70% of your daytime DHT levels anyway, so it really doesn't matter. At the same time, taking constant regular doses of finasteride keeps your DHT levels at a constant low anyway, so just pick a time and try to stick close to it.
