It is a very liver toxic compound, so make sure to keep the cycle within a maximum of 6 weeks, and use a good liver supporting supplement, such as N2Guard. You can use it as a kick-starter, but it would be nice to know what sort of cycle you are going to run, because it is possible that superdrol might be a good finisher as well for you. By using it as a kick-starter you will not go wrong, but if your other compounds are already acting fast enough, you would benefit more by using it closer to the end of the cycle in order to polish your gains.
