I’d like to last them longer, so should I switch the dose? Will it be any different? Like worse results etc? I’ve been using 2,5 fin for 4 months.
Lowering your fin dose to 1.25 mg might not make a huge difference since most DHT suppression happens at lower doses. Check your hair growth over time to see if the lower dose works for you. Keep in mind, it might take a while to notice changes. If you want detailed advice, check the Beginners Guide.
