I read this with hope the "Cash" may possibly know if this may be face thx much

"Hope this post helps your question, i too am a hair fanatic so i understand your pain bro...

First off, let me preface this by saying that this is true, in certain contexts.
However, I'm an advocate of including testosterone in every cycle, so my explanation is with the assumption that one will be using nandrolone in addition to testosterone

For those that do not know, testosterone converts to DHT via the 5 alpha reductase enzyme. DHT is far more androgenic than testosterone and is the main contributor to MPB in those genetically predisposed.

finasteride is a 5 alpha reductase inhibitor, and therefore limits the conversion of testosterone to DHT via competitive inhibition.

Nandrolone itself is a 5 alpha reductase inhibitor (although it yields DHN in the process). So less DHT is produced if nandrolone is present. Also, DHN is much less androgenic than nandrolone and much less androgenic than DHT. So, finasteride with deca (nandrolone) should both work to reduce DHT levels, and since finasteride will inhibit 5a reductase, it'll also keep levels of DHN lower too.

The misconception that deca with finasteride is a bad combination stems from the the days when deca only cycles were more common If one were running a deca only cycle (or any deca cycle without test), then finasteride would be a poor choice, because DHN is less androgenic than nandrolone. However, since we're assuming test to be included in a deca cycle, and both test and DHT are far more androgenic than nandrolone, if your goal is preventing the formation of the most androgenic compounds, then both deca and finasteride work together to reduce DHT formation.

To sum things up, if you're running a test + deca cycle and are worried about MPB (and you're susceptible), then including finasteride is a far better option than NOT including it, although the nandrolone will help to reduce DHT formation on its own to some exten"

reason for my interest is many mods on steroidology say testosterone replacement therapy (TRT) dose wont cause hairloss (i wish) and the n most don't like dht inhibitors. so would a small dose of deca be more wise that propecia? or atleast draw blood read dht run deca recheck dht levels ?

all thoughts appreciated

i really think we should beat this dead horse a bit...you will all see the longet your on testosterone replacement therapy (TRT) you hair will thin.
 
There are some inaccuracies in that post.

First, nandrolone IS NOT a 5-alpha reductase inhibitor. That is wrong. Nandrolone interacts with the 5-alpha reductase enzyme to reduce to dihydronandrolone, a less androgenic compound then nandrolone. It in no way acts as an enzymatic inhibitor.

Second, 5-alpha reductase is has a sequential binding affinity for testoterone over nandrolone. That means that it will bind to test first and more vigorously if test is available to be bound. Why - because the reaction requires less energy and proceeds more efficiently. If not it will bind with nandrolone in the absence of available test. The binding of 5-alpha reductase is specific and there is no 1 for 1 competition between test and nandralone for binding affinity to the 5-alpha reductase enzyme.

Finally, I think i understand where the poster is trying to go and in essence there is some truth to what is stated but the science is totally wrong on how the poster got to there. I think his point is that unreduced nandralone is less androgenic than DHT. That is correct. If one had to pick his respective poison, then they should pick unreduced nandrolone since it would have less of an impact on the hair follicles than DHT.
