I think your going off the track here an loosing the basic principles...
You want to get bigger, your going to have to hold some water, some bloof, look a little smooth, thats just the way it is. Your not going to gain no fat with some Tren and growth in there so its only a short run back before you back to being cut..
Your worrying about LDL and HDL.. Look your pumping your body with hormones, there will be consequences for these actions down the line.. Your body is far beyond what it could attain naturally, there is always a price to pay for this, nothing is a free ride.. it may not be your arteries that pay the price but something will. All you can do is be as healthy as you can and like it has already been suggested take fish oils, good fats, swallow some Argine if you feel it will help, eat your fruits, veg, good balanced healthy diet, keep the ale to a minimum etc etc and do your best.
Personally you want to get bigger, you wanna do it now before the weather kicks in and you can show off what you worked for.. bloof a little until April with some compounds that will cause you to thicken out then just shift it like you did to get to this point!
