I have had good experience with the QV 300 it is in a red bottle right? With a little ugly dog on it. It is good stuff. I am only 21 and I am doing a lite cycle as weel. When I the deca you are doing I got great gains and with the whinny with it you should get some solid gains with little water. Also the deca makes my joints feel great, making me be able to lift more. I would say go for it. Some guys might tell you to do more, but untill you get more experience do it in moderation.
