Ok here's the thing with that. Mast, tren, primo etc are not DHT. Lowering systemic DHT will take care of the DHT from the test you're taking but not the androgens from those compounds as they will still bind to the hair follicle. Remember 5a reductase inhibitors prevent conversion. The drugs above dont need to be converted.well now you’ve scared me into running low dose propecia considering i’m about to run mast, tren AND winny hahahaha
So for my proposed cycle I don't have much to worry about other than DHT from the test and the small amount of DHB from the boldenone. NPP produces DHN which doesn't seem to do anything negative to hair. I'll use pumpkin seed oil to drop the DHT systemically to also protect my prostate.
RU58841 is part of the hair protocol I use which is an anti-androgen so in theory it can block other androgens from binding. I've even seen a post on Reddit where someone actually grew hair back using RU while taking tren and mast
