A “stronger DHT block” TikTok is not a diagnosis. Photograph; ask a prescriber about labelled indications.
Type II 5AR is the main story in prostate and many scalp discussions of finasteride 1 mg. Type I is another isoform. Dutasteride’s dual block is why some countries approve it for hair and others keep it off-label. This page will not invent a PMID. Related: dutasteride-versus-finasteride — different URL.
Do not mash leftover 5 mg prostate tablets as a hair stack. Pregnancy pictograms apply. Do not double minoxidil as a 5AR substitute.
A partner who is pregnant and handled crushed tablets should call their clinician. This is not medical advice.
