Ok, I am afraid I can't help you with magnets. I have done zero reading into that subject.
Olive oil is used as a carrier fluid and penetrator of the skin for herbs. Eucalyptus oil can be added to help in skin penetration. The idea is to penetrate the skin and directly "target" the recepters in the tissue. Fenugreek, fennel, and other herbs are usually soaked in the olive oil.
Massage itself aids in blood flow and distribution through the tissues.
I will be leaving you some links to this information on herbal massage oil and skin penetration. I won't say that you can't develop from massage alone. Your body may be sensitive to estrogenic compounds and will respond to herbal massage. Several of thel G girls here on this forum have had sucess with massage alone. (see link at bottome) The mental aspect of NBE cannot also be ignored. I would ,however, recommend taking some sort of anti-testoterone herb. Saw Palmetto extract has worked well for me in blocking the formation of DHT and cutting back on test. I have heard of men taking herbals without a blocker and getting some small results. The results were slow in coming and they did end up taking too much herbs to effect change. I don't see where taking SP would be a problem in giving blood, but it is not a subject I am versed on.
The main thing that I have read concerning massage alone is that you must be consistant in the aplication of the program. I am listing you several links to threads dealing with fenugreek ,internal and external, with massage. A thread on certain kinds of diets and massage. The next to the last link is to tigerlilys program page. She reported growth with just massage. Eating a certain foods in her diet and leaving out certain things. Mostly chicken feet. There are many paths to breast enlargment. You just keep searching until you find what works for you. The last link here is to a page to help explain tigerlilys massage program by cocolily

Here is the two pages I first mentioned on a herbal olive oil and skin penetration.
This page is by fennel fairy on skin structure and adsorbtion. Here is the link.

This is a very useful page by Wahaika. It is about a herbal program for women, but it has useful info. on herbs and a recipe for a breast batter mix.

I use a mix of steeped fenugreek and fennel seed. I take a recipe for tea and up the fennel content a little. I tsp and a half of fennel to a cup of water. Added into a mixed cream of Lubriderm, lavender essential Oil body lottion with Eucalyptus essential oil. Can't say how effective this is, and is not the cheepest way to go. Will probably change mix to a oil base like oilve oil or baby lotion next batch. Gotta soak the stuff in the oilve oil first. See link for more info. I would recomend doing a search through the forum to find even more info. But this information will give you the basic idea.
I hope you find this info useful.
Best wishes and happy journey
