Winstrol and Deca are a logical combination because nandrolone (Deca Durabolin) is effective at the androgen receptor and stanozolol (Winstrol) is effective in non-AR mediated mechanisms. Furthermore, stanozolol binds to the progesterone receptor but is not progestogenic, whereas nandrolone is progestogenic. Thus, Winstrol may very well block the progestogenic effect of Deca that can lead to bloating, gyno, and/or impotence.
really should have realized this before, since I had reports of this combination working very well. But somehow I had not realized the rather obvious reason above for why Deca would show less side effects when Winstrol is used.
On the same subject, while it is true that nandrolone can aromatize and does aromatize to some extent, the usual claim that it aromatizes a great deal is not true. The progestogenic effects are mistakenly being called estrogenic effects.
Two pieces of evidence support this:
1) One study found that Deca at both 100 mg/week and 300 mg/week actually reduced serum estradiol levels by about 65% compared to starting values. This presumably is a consequence of the reduction in testosterone, which was by a comparable percentage, and with little nandrolone being converted to estrogen.
2) On a Deca-only cycle, clomid is reported not to block bloating.
3) High levels of progesterone kill sex drive, and this problem has been observed with Deca. While it does not "convert" to progesterone, it acts like that hormone at the progesterone receptor. So, how to use the Deca and Winstrol? Why not try 800 mg Deca on the first injection, and then 400 mg once per week after that for four to six weeks, and use 50 mg/day Winstrol. It could then be continued at 50 mg/day for another two weeks, since there is still plenty of Deca in the system to promote gains and also to make recovery impractical anyway, and then reduced to 50 mg every other day in order to allow recovery.
