Are you not curious what you could regrow on 2.5mg Dut if you can handle the standard dose? What's stopping you?

We know that unlike Fin, Dut offers better chance of regrowth the higher the dose as scalp DHT is further reduced without necessarily increased risk of side effects if one can already tolerate 0.5mg and there are many guys here that could attest to that. There is even a guy here who makes his own 4mg capsules and his density went double within a year. Why aren't we all going for higher doses to maximise the gains? Ignorance? Fear? Affordability? Availability?
