Durabolin 300 / Deca – Sis labs
The base of Deca 300 is Nandrolone decanoate. This oily injectable is typically used in an eight to twelve week cycle, and most beginners use it at a rate of 100 mg per week. If you’ve worked with it before, though, you may want to increase to 200 mg per week. Natural testosterone suppression is the most common side effect.
