Just make sure you have a good PCT plan set up or you will be hurting when you get off them. Your system could crash if you do not take an anti-e and natural test booster. I would take a liver detox as well.
Also make sure to keep your EFA's up as some of these products can wreck havoc on your lipid profile in a bad way. Take some fish oil, flax in shakes, etc. to boost your EFA's and I would take the pro-hormones with fattier meals (meats, oil in shakes, nuts, etc).
as far as diet goes you should eat whole eggs every morning... the cholestrol and fats in the eggs are absolutely vital for production of testosterone. and synthesizing all of the protien you will be eating. also, eggs are one of, if not THE most complete sources of protein available. go low carbs...and replace those calories with healthy fats and red meat fats. youll be HUNGRY taking those products. stick to proteins and fiberous veggies. BROCCOLI! broccoli will prevent the conversion of all that testosterone into estrogen, will clean out your bowels, will bind to any unnessecary fats in your digestive tract, will help you better digest your proteins, and will keep you full!!
to summarize.. EGGS, BEEF, BROCCOLI!!! (and if you have a quick metabolism...whole milk!)
