Any scientific studies to back that up? And what's considered high?
Not everything black and white, like I said.
Of course you can. Most I'd take is 100mg. My body at 38 is probably making a lousy 25mg per week by itself. 100mg would make a massive difference, while finasteride would probably still block enough scalp dht to keep me whole. Do I know that? No. But I'm willing to take the risk. If I saw anything awry, I'd stop. But I doubt I would at that level. For instance, a normal cycle of test is at least 250mg per week, at minimum. More likely 4 to 500mg per week.
