Deca Nandrolone deconoate 300mg 10ml is one of the most popular injectable steroids. It’s popularity is likely due to the fact that Deca exhibits significant anabolic effects with minimal androgenic side effects. Considered by many the best overall steroid for a man to use (side effects vs. results) Deca is most commonly injected once per week at a dosage of 200-400mg. With this amount, estrogen conversion is slight so gyno is usually not a problem. Also uncommon are problems with liver enzymes, blood pressure or cholesterol levels. At higher dosages, side effects may become increasingly more frequent, but this is still a very well tolerated drug.
