From what I understand, Gh will actually improve cholesterol, increasing your HDL while lowering LDL (bad cholesterol). I have not seen this in my own life. I use GH year round. But I have read a lot of info to say that this is the case. I usually have to fight to keep my cholesterol in balance due to the use of AAS. Make sure that you get plenty of fiber in your diet and supplement with at least 3g fish oil.
