n atural testosterone levels and thus allowing the aromatase enzyme less substrate to work with, Deca nonetheless can cause gyno in some individuals. Furthermore, just as progesterone will to a point increase sex drive in women, and then often decrease it as levels get too high, high levels of progestogenic steroids can kill sex drive in male bodybuilders, doses of 400 mg/week. The long half-life of nandrolone decanoate makes it unsuited to short alternating cycles, but suitable for more traditional cycles, with a built-in self-t

Incidentally, this progestogenic activity also inhibits LH production, and contrary to common belief, even small amounts of Deca are quite inhibitory, approximately as much so as the same amount of testosterone.bodybuilding,in avoiding aromatization of nandrolone.

The drug is moderately effective at because while moderate Deca-only use actually lowers estrogen levels as a consequence of reducing n

To some extent, nandrolone aromatizes to estrogen, and it does not appear that this can be entirely bloapering effect in the weeks following the last injection.though there is a great deal of individual variability as to what is too much.cked by use of aromatase inhibitors – indeed, aromatase may not be involved at all in this process (there is no evidence in humans that such occurs) with the enzyme CYP 2C11 being in my opinion the more likely candidate for this activity.
