The number one concern men have about starting a hair loss protocol is sexual side effects. It's the reason a lot of people never start finasteride or dutasteride at all, and it's based on a story that's been dramatically oversold.
The actual data: the side effect rate for finasteride is only 1.7% above placebo. One or two people out of a hundred may experience any effect at all, and for most of them the side effects resolve completely within one to three years.
If you're still nervous, there's a simple solution. Add 5 mg of tadalafil (generic Cialis) daily. Andrew Huberman recently covered this on his podcast. Elite athletes are now taking daily tadalafil because of its broader health benefits. It's linked to reduced Alzheimer's risk, better cardiovascular function, and improved circulation across the body. Think of it as a general biohack.
In the context of hair loss, taking daily tadalafil alongside a DHT blocker essentially removes any concern about sexual side effects. Most users report that their sexual health is actually better than it was before starting the protocol.
The fear here is much bigger than the risk. Don't let bad information keep you from a treatment that works.
