you shouldnt stack a stim with a stim, so if your on white flood avoid the leviathan. I would also recommend you cycle stims on and off from time to time. I seem to get weird reactions from long time stim use. cycling them off for me is the best way for me to use them in my opinion. Purple wraath is EAA, (essential ammino acids) lots of debate has been going on about this. I believe purple wraath or any amino acid is a MUST for cutting. I also believe that there are added benefits such as less rest time, more recovery or even better faster recovery. From what I can tell from purple wraath, it contains citrulline malate. I love citrulline malate as a 2-3g dose helps my endurance at the gym. Im not sure what 1g will do for you but im sure if you take, 2-3 servings of Purple Wraath you'll feel as if your endurance is up.
Green Magnitude and White Flood is a great combo. Personally, I saw lots of results on it. Im cycling those two off for now, as I believe in cycling most of my supplements except for protien. compared to when I was on Green Mag and White Flood, I kept most of my gains in the lift department but I definately feel the lack of energy. While on White Flood, I always recieved a clean but not too crazy burst of energy on it. It was a good feeling. Here's my recommendation for you, 1 serving GM, 1 serving White flood, and 2 or 3 servings of Purple Wraath. I believe with this stack you'll see strength gains, clean energy, more endurance and better recovery. best of luck to you. just my 2 cents.
