I would not front load your first cycle.
I would start the AI at week 2.
I wouldn't go over 1.5g of protein per pound of bodyweight. Fill with carbs.
Slowly increase your calories as you gain weight on cycle.
It is OK but not ideal to start hCG a little late.
You may find that you need a little more than 500ius of hCG a week. I like 750.
My hCG did infact show that I was pregnant.
At 5' 11" and 175lbs I would strive to put on size. Worry about leaning out at a future date.
