You are really on the wrong website...actually you are on the right one its just that no one here with any credibility is going to give you advice on how to do a cycle much less a 500/600 deca/test cycle at 19 years of age. Stop the cycle and get on the nutrition and workout forums and work on building a natural base, other than that best of luck to you and you are very likely to need it as long term damage to your HPTA system is likely in your future. PS no way are you at 4.7 BF
