You are quite bold. I don't touch any steroids anymore, despite using both minoxidil and finasteride. I would normally say that finasteride can't save your hair, when you are running other steroids than testosterone, but now I think that it does more than just suppressing DHT.
I started to use finasteride in late June, and one week later, I started a cycle with SARMs. My testosterone quickly dropped to mere 50 ng/dl, so you would say that finasteride couldn't work via DHT suppression, because there couldn't be much DHT left in the body. At the same time, I have never observed any signs of regrowth during a SARMs cycle. Yet I noticed an unparalleled regrowth after mere 6 weeks of finasteride use. So, the reaction of finasteride with the enzyme 5-alpha reductase must have led to some large-scale chains of chemical reactions in the body.
Still, I would be very careful, when using drugs like trenbolone.
