btw cashout, since Winstrol (winny) is also a dht derived steroid, it would also not interact with th3 5AR enzyme correct?
also, what about deca? can nandrolones bind to the enzyme?
As a general rule of thumb, DHT-reduced AAS are far less androgenic and will have a significantly less negative effect on one's hair.
There is one exception - Anadrol. It is DHT-reduced but it has some very uncharacteristic properties for DHT-reduced compounds. If you value your hair, stay away from Anadrol.
Winny gets a bad rap for contributing to hair loss but that is just not accurate. Winstrol (winny) is a very mild androgen and really doesn't bind strongly to the AR. Winstrol (winny) gets it bad rap from the fact that nobody does Winstrol (winny) Only cycles. In a cycle, folks are most often stacking and Winstrol (winny) and test or even tren. When they start to have problems with hair loss they blame the Winstrol (winny). In truth, it is the test and tren that may have been stacked along with the Winstrol (winny) that created the issue.
Deca interacts with the 5AR to reduce to DHN - a less androgenic isomer of nandrolone. So, if you are running Deca, you do not want to use Fina/Duta b/c they will inhibit the nandrolone reduction and actually increase the potential for side effects. FYI, deca is actually a very hair line friendly AAS, just don't run fina if you use it.
Tren is a whole different beast. B/C of its structure it doesn't reduce via the 5AR. However, it is the most androgenic commercial AAS ever produced and nothing will protect your hair line from the effects of tren.
So, to keep your hair, use test with Fina.
If you must stack your test, stack test with EQ, since EQ doesn't reduce via the 5AR in any meaningful amount. Actually it does reduce but in such a tiny amount that its really irrelevant in this discussion.
If you want all your hair to fall out fast run a good test base cycle with tren and a-bombs.
