I read that vitamin A lowers excess 5a reductase and increases androgens while lowering the "end-of-chain" hormones like DHT. I think low vit A is definitely a player in MPB but it's involved in extremely complicated biochemical processes so IDK if it's safe to supplement. It can greatly increases oxidative stress, iron/PUFA-related damage, blood pressure, etc. if your system can't handle it.
