I was glad to see that you decided to run the Nolva an not
Clomid. IMO, clomid should be last option.
Real sources of protein ... good carbs and fats. Don't be afraid to eat.
If you have enough for 12 weeks and you are liking the progress - I say go ahead and go the 12 weeks on ... you are going to react the best to your first cycle ... max it out!
1" is a little short for your thighs, but you look lean enough. Just make sure you get deep into some muscle, inject slow, and cycle spots.
Good luck, will be watching your progress. Props for doing the research ahead of time.
