Nandrolone Decanoate 300 is not known as a very "fast" builder. The muscle building effect of this drug is quite noticeable, but not dramatic. The slow onset and mild properties of this steroid therefore make it more suited for cycles with a longer duration. In general one can expect to gain muscle weight at about half the rate of that with an equal amount of testosterone. A cycle lasting eight to twelve weeks seems to make the most sense, expecting to elicit a slow, even gain of quality mass. Although active in the body for much longer, Nandrolone Decanoate 300 is usually injected once per week. The dosage for men is usually in the range of 300-600mg. If looking to be specific, it is believed that Nandrolone Decanoate will exhibit its optimal effect (best gain/side effect ratio) at around 2mg per pound of bodyweight/weekly. Nandrolone Decanoate 300 is also a popular steroid among female bodybuilders. They take a much lower dosage on average than men of course, usually around 150mg weekly. Although only slightly androgenic, women are occasionally confronted with virilization symptoms when taking this compound. Should this become a concern, the shorter acting Nandrolone Undecanoate 200 would be a safer option.
