Deca: The Best For Mass?


Deca, or nandrolone decanoate, is considered the gold standard anabolic steroid for building muscle with minimal side effects.  It binds with a higher affinity to the androgen receptor than testosterone and is more anabolic and less androgenic. It less readily converts to estrogen than testosterone and it converts to a weakly androgenic metabolite DHN instead of the extremely androgenic DHT.  In a 2004 study researchers determined 200 mg of nandrolone administered for 8 weeks resulted in 5 pounds of fat free muscle, and 3 pounds of water with 0 pounds of fat gained vs a control.  These results are less impressive than previous studies on testosterone enanthate or surprisingly a recent study on 1-Andro, a prohormone.  


Benefits & Side Effects

200px-Nandrolone.svgDeca is one of the closest anabolic steroids to being purely anabolic. The only thing even more purely anabolic is 1 Andro. As stated above, it is not very androgenic nor is its metabolite, but it is a strong binder of the androgen receptor so it could cause hair loss in genetically predisposed individuals.  These androgenic features could cause acne, as well.  Normally a 5 alpha reductase inhibitor would decrease androgenicity but in deca it would not help and could actually make it more androgenic because it doesn’t convert to the weaker DHN.  

Estrogen conversion is only 20% of testosterone, but nandrolone binds weakly to the progesterone receptor, 20% as great as progesterone itself. This coupled with the very low androgenic qualities means in deca only cycles you will see dramatic wet side effects: water retention, fat accumulation, gynecomastia, loss of libido, impotence.  

To correct this use of a testosterone base steroid or prohormone is necessary. this will provide the basic amount of DHT to balance out androgenic and estrogenic qualities and the testosterone to help with sex drive.  The old belief is if you can get away with 200 mg of testosterone for 400 mg of deca you’re lucky, some need to use double the testosterone of the deca amount, so for 400 mg deca you would need 800 mg testosterone.


Legal Alternative To Injectables

amsultimate_largeMy suggestion is to use a legal alternative.  The current prohormone clones are scientifically proven to be almost as effective and far safer than home made injectable steroids. And their legal, so you avoid jail time and social stigma.  19 Nor Andro converts to deca, and 1 Andro converts to 1 testosterone, which is a non aromatizing, non reducible version of testosterone which is more potent then regular test.  Additionally a university study showed it to put 4 pounds of muscle on and burn 7 pounds of fat. Thats way better than the study on injectable deca. In case you want to use a prohormone that converts into testosterone so it can then, in turn, convert to estrogen and DHT then use 4 Andro.  I have compiled a stack with all three, which mimics the effects of Test, EQ, and Deca which is available here. That stack has PCT included and will last 12 weeks at minimum dose, although I advise a 8 week cycle.
