BOldenone is not 5-alpha reduced in the human body to any appreciable degree at all. Propecia is of no relevance.

And
All androgenic side effects occur via androgen receptor stimulation. All AAS activate this receptor, and all potentially cause such side effects. T is a more potent androgen than most agents of course because it is reduced via 5-alpha reductase to DHT (a more potent steroid) in many androgen target tissues. Although a 5-alpha reduced version of boldenone (1-testosterone actually) is a more potent activator of the AR than boldenone, boldenone also has an extremely LOW affinity for 5-AR. 99.8% of the dihydro metabolites are relatively inactive 5-beta's. There are virtually no 5-alpha metabolites of boldenone found in humans. This is why Propecia, which inhibits 5AR, can lower the androgenic nature of T but not of boldenone.
