Well, I could give you the cheeky answer which goes something like "Anything mentioned in this thread because self-suggestion is a thing", or I could give you an intellectual answer answer like "Well, the most effective physical effect files are those that derive their changes from mindset changes. Most jocks get ripped by working out, not by listening to suggestions for their muscles to get bigger."
Or... I could give you what you're explicitly asking for, which would be "No Penis Loop", which is (arguably) the first physical effect file one encounters when looking up free files in order of descending rating.
