Forgive me, but I am a bit confused. Finateride/propecia is supposed to counter male pattern baldness. Are you saying that if one add Deca, it has the reverse affect?
All I remember is when I was doing my first cycle I was gonna stack deca with my test but then had second thoughts when I read about the deca and finasteride combination causing more hair loss.
There is a lot of info about it online...but now there are conflicting reports so I don't know what to believe. Here's one post I found. Personally, I use propecia and find it to help with hairloss but I still won't stack deca with it just in case.
"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 extent."
