Yes, lipid profile is the breakdown of your cholesterol. HDL, LDL, VLDL, triglycerides, and total cholesterol are the usual numbers taken. Oh, and LDL to HDL ratio. HDL is the "good" cholesterol, LDL is the "bad" one, oral steroids, strong androgens, and low estrogen levels( which AI's like arimidex can cause) can lower HDL and raise LDL, giving you a bad lipid profile. This is only temporary though and usually reverts to normal within a month of cessation of usage. I take supplements specifically talored to avoid this as much as I can when on.
