those two things are pretty much the very things that Deca does NOT produce. Deca is not androgenic in that instead of converting to DHT it converts to DHN , which then binds to DHT receptors and occupies them yet doesn't illicit any androgenic effect . also natty test levels are going to fall off so you won't be getting more DHT coming in either . which is also why your estrogen levels will also begin falling off.
over time you'll have no androgenic load and no estrogenic load to work with (and thus struggle with sex drive and erection ability).
Then there is a third thing . Deca is a progestin thats going to bind to progestin receptors. this in turn can elevate Prolactin levels, which when way too elevated can also cause erection issues .
and an un-related to deca its fourth thing that often times happen , guys start taking a high dose of an AI from day one of their deca cycle , mistakingly thinking they need it cause they think deca aromatizes a lot (which it doesn't, again your e levels will go down on deca, not up) , and then they crash their estrogen super quick and of course have lethargy, no sex drive, etc ..
so whats the best bet. stack some androgenic and aromatizing based compounds in with your deca. first one is clearly test because it converts to both DHT and Estrogen . also you can stack another androgen like Masteron which will lower SHBG , which then thus allows for more androgenic activity by freeing up bound DHT into the blood stream . Mast will also blunt some of the progestin effects . and also you can add in low dose Dbol to get even more estrogen if need be.
