Dutasteride and finasteride have similar risk profiles despite Dutasteride blocking more types of 5AR in the brain. Some users report no mood issues with either drug, and it is suggested that Dutasteride's larger molecular size may limit its ability to cross the blood-brain barrier.
Epristeride is a selective 5 alpha reductase type 2 inhibitor that may reduce scalp DHT similarly to finasteride, with potentially fewer side effects. It is suggested that combining epristeride with finasteride or dutasteride could enhance hair loss treatment effectiveness.
Rosemary extract showed high inhibitory activity against DHT, similar to finasteride and dutasteride, but the conversation includes skepticism about its effectiveness in humans since the study was done on mice and rosemary oil is often considered ineffective based on personal experiences. Some suggest trying rosemary oil alongside other treatments, while others emphasize the difference between the extract used in the study and the oil.
PP405 from Everychem is likely fake and potentially harmful, with concerns about its stability and the risk of using the wrong MPC inhibitor, which could damage hair follicles. The real PP405 was studied under strict conditions, and DIY attempts are discouraged due to unknown formulation and quality control.
