THeres a whole bunch of questions there...
1-ad powders is sold at kilosports I think. Capping 1,4ad is difficult - the powder looks much denser than say 4ad so manual capping is a pain. I don't know how transdermals can give you an infection, most people here like it alot. For PCT do a search read stickies/FAQs for a start, imo 6oxo for 1ad is ok but nolva is not more expensive.
If you can't afford extra food, and all your supplements for a proper then wait until you can. Don't be like the other nutcase in another thread who wanted a 1wk cycle.
Lastly you might want to bring your bf% down naturally abit first, should be easy if you are a young college student.
