It's been discussed 1000 times I know, I am still confused after using the search function a lot. I'm running 500 test and 400 deca... I see a lot about running deca higher, but is it. Going to hurt potential gains from running the test higher? I'm on week 4 and I had a high libido before but I'm noticing its down a little, I go through cycles of horniness so I could be that, but couldn't it be the deca... And would upping the test a little. Remedy it if it's indeed that?
