With respect to anabolism, Deca is only slightly stronger than Testosterone. It has a strength rating of 125, while the strength rating of Testosterone is 100. But Testosterone has a very low androgenic rating of just 37, and this makes it more suitable for people who experience side effects of Androgenic drugs. Deca is very important in the lifestyle of a bodybuilder or athlete as well as Testosterone that is equally as important. Knowing everything there is to know about these compounds will only help you in the long run.
Nandrolone has very low activity of Estrogenic effects as it binds very badly with the enzyme, aromatase.
Another point is that, Aromatase is responsible for converting Androgens into Estrogen. Only approximately 20% of Nandrolone is converted into Estrogen which is lower than Testosterone’s conversion percentage.
It is because Deca is a Progestin, like all other 19-nor compounds, its Estrogenic activity is so low. If you delve deeper, you will find out that Nandrolone is Aromatized into Estrogen in the liver. However, in other areas of the body where normally there is a high rate of Estrogenic conversion, like in fat tissue, Deca is not conducive to Estrogenic conversion.

Deca is categorized as a Progestin and classified as a 19-nor compound because it does not have the 19th carbonate that Testosterone has. Being a Progestin type drug, it has an attraction for the Progesterone receptor. This can result in some possible side effects and problems that only 19-nor compounds exhibit, and are not found in other anabolic steroids.
Nandrolone possesses very low Estrogenic activity and binds very poorly with the Aromatase enzyme, which is the enzyme responsible for the conversion of Androgens into Estrogen. Only about 20% of Nandrolone is converted into Estrogen in comparison to Testosterone’s conversion rates. Deca-Durabolin experiences a very low Aromatization rate into Estrogen, making Estrogenic side effects less of an issue compared to other anabolic steroids. This is one of the aspects that those in the fitness and bodybuilding industry love about Deca. Users will not experience “extreme” water retention (if any) while cycling with this compound. But, keep in mind that every individual will respond differently to different steroids at different dosages.
