Like Deca-Durabolin, Dynobolan is a nandrolone that can produce some very good gains in muscle mass if taken over a long period of time, say a 12-week cycle. Side effects are minimal, especially if injected at only around 400 mgs/week or less. The usual side effects for nandrolones are possible with Dynabolan acne, water-retention, impotence and hair loss, but are rare and mild if the doses are kept reasonable.
