Fin and dut lower DHT in the whole body. That helps normal MPB and can blunt extra DHT from test, but primo is already DHT-like so it can still hit the follicle receptor. Those pills also drop systemic DHT, which a lot of people do not want on cycle.
KX826, clascoterone, and RU do the other job. They try to block the androgen receptor on the scalp and leave blood hormones alone. In theory test and primo can still work systemically while the scalp lock is harder to turn. That is why a topical AR blocker matches this stack better than a 5AR inhibitor.
KX826 sounds strongest in that group because it binds the receptor very tightly on paper, is designed to break down if it goes systemic, and actually has Phase 3 hair-count data. Clascoterone is the same mechanism with a cleaner Western trial path. RU is mostly anecdote and no real RCTs.
Still not a guarantee. No studies on test/primo. High androgen load can overpower a topical. Not FDA-approved for hair. Best current logic for cycle hair protection without crashing DHT everywhere, not the proven best drug.
