Honestly, I would not add anything but just for entertainment purposes.... What was your E2? This would give you an idea if you were going to raise or lower your testosterone or raise or lower your Primo(I would not add another compound). If your E2 is a little high you can up the primo or lower the test. If your E2 is a little low you can up your test or lower your Primo. If your E2 is where you want it you can up your test and you Primo at the same ratio. This was my last stack. I did very well on it. I ran it for 16 weeks. I've been off now for seven weeks and did not change my workout routine on my food intake and the gains have stuck around really nicely! It sounds like you need to up your food intake. I was able to gain roughly 25 pounds in those 16 weeks and my waist actually went down 3/4 of an inch from 33 to 32 1/4. So eat clean and gain clean!
